Photos and videos can be accessed from Flickr without the need to register an account, but an account must be made to upload content to the site.

==History==
Flickr was launched on February 10, 2004, by [[Ludicorp]], a [[Vancouver]]-based company founded by [[Stewart Butterfield]] and [[Caterina Fake]]. The service emerged from tools originally created for Ludicorp's ''Game Neverending'', a web-based [[massively multiplayer online game]]. Flickr proved a more feasible project, and ultimately ''Game Neverending'' was shelved.<ref>{{cite news|last=Graham|first=Jefferson|title=Flickr of Idea on a Gaming Project Led to Photo Website|work=[[USA Today]]|date=February 27, 2006|url=https://www.usatoday.com/tech/products/2006-02-27-flickr_x.htm|access-date=September 4, 2006|archive-date=July 14, 2012|archive-url=https://web.archive.org/web/20120714014139/http://www.usatoday.com/tech/products/2006-02-27-flickr_x.htm|url-status=live}}</ref> Butterfield later launched a similar online game, [[Glitch (video game)|''Glitch'']], which was shut down on November 14, 2012.<ref>{{cite web|url=http://www.fastcompany.com/1783127/can-a-game-that-wants-you-to-play-nice-become-a-blockbuster|title=A Flickr Founder's Glitch: Can A Game That Wants You To Play Nice Be A Blockbuster?|publisher=Fast Company|date=September 27, 2011|access-date=September 30, 2011|archive-date=July 12, 2012|archive-url=https://web.archive.org/web/20120712030522/http://www.fastcompany.com/1783127/can-a-game-that-wants-you-to-play-nice-become-a-blockbuster|url-status=live}}</ref><ref>{{cite web|last=Lunden|first=Ingrid|title=As Flickr Co-Founder Butterfield Shuts Down Glitch, Is He Planning A New Photo Service?

Early versions of Flickr focused on a [[chat room]] called FlickrLive, with real-time photo exchange capabilities.<ref>{{cite web|last=Tynan|first=Dan|title=Photo Sharing Gone Wild|url=http://www.pcworld.com/article/116576/article.html|work=[[PC World]]|access-date=July 26, 2013|date=June 24, 2004|archive-date=October 1, 2020|archive-url=https://web.archive.org/web/20201001131436/https://www.pcworld.com/article/116576/article.html|url-status=dead}}</ref> The successive evolutions focused more on the uploading and filing back-end for individual users and the chat room was buried in the site map.

In addition to being a popular website for users to share and embed personal photographs and an [[online community]], in 2004, the service was widely used by photo researchers and by bloggers to host images that they embed in blogs and [[social media]].<ref>{{cite magazine | first=Daniel | last=Terdiman | title=Photo Site a Hit With Bloggers | url=https://www.wired.com/culture/lifestyle/news/2004/12/65958 | quote=Flickr enables users to post photos from nearly any camera phone or directly from a PC.

(owned by Verizon at that point) sold Flickr to [[SmugMug]].<ref>[https://www.theguardian.com/technology/2018/apr/23/flickr-bought-by-smugmug-yahoo-breakup "Flickr Bought by Smugmug as Yahoo Breakup Begins"] {{Webarchive|url=https://web.archive.org/web/20240622050031/https://www.theguardian.com/technology/2018/apr/23/flickr-bought-by-smugmug-yahoo-breakup |date=June 22, 2024 }}, ''[[The Guardian]]'', April 23, 2018.</ref>

In early May 2019, SmugMug announced the migration of Flickr data, involving 100+ million accounts and billions of photos and videos, from the servers of former owner Yahoo! to [[Amazon Web Services]] (AWS), in a planned 12-hour transition to occur on May 22, 2019.<ref>{{Cite web |url=https://blog.flickr.net/en/2019/05/08/planned-maintenance-and-flickr-downtime/ |title=Planned maintenance and Flickr downtime |date=2019-05-08 |website=Flickr Blog |language=en |access-date=2019-05-23 |archive-date=December 6, 2020 |archive-url=https://web.archive.org/web/20201206133924/https://blog.flickr.net/en/2019/05/08/planned-maintenance-and-flickr-downtime/ |url-status=live }}</ref>

In May 2023, Flickr announced the development of the Print Shop feature that was being tested with a list of approved sellers. The Print shop feature allows photographers to sell prints via a storefront, and allows purchases from consumers. The feature was to allow only approved members access to it, but the criteria for that were yet to be announced.<ref>{{Cite web |last=Segarra |first=Lisa Marie |date=2023-01-17 |title=Flickr to Allow Photographers to Sell Prints |url=https://petapixel.com/2023/01/17/flickr-to-allow-photographers-to-sell-prints/ |access-date=2023-05-30 |website=PetaPixel |language=en |archive-date=May 30, 2023 |archive-url=https://web.archive.org/web/20230530113628/https://petapixel.com/2023/01/17/flickr-to-allow-photographers-to-sell-prints/ |url-status=live }}</ref>

===Corporate changes===

==Features==
===Accounts===
Flickr has always offered two types of accounts: free and paid. Until January 7, 2019, free accounts had up to 1 TB of storage. On January 8, 2019, the account offerings changed.<ref>{{Cite news|url=https://www.theguardian.com/technology/2018/nov/02/flickr-delete-millions-photos-reduce-allowance-free-users/|title=Flickr to delete millions of photos as it reduces allowance for free users|work=The Guardian|access-date=November 6, 2018|archive-date=November 3, 2018|archive-url=https://web.archive.org/web/20181103011339/https://www.theguardian.com/technology/2018/nov/02/flickr-delete-millions-photos-reduce-allowance-free-users/|url-status=live}}</ref> The free option is limited to 1,000 photos or videos stored, with videos limited to three minutes. After January 8, 2019, members over the limit could no longer upload new photos to Flickr. On February 5, 2019, a free account's older content would be deleted automatically if it contains more than 1,000 photos and they do not subscribe to the paid service tier,<ref>{{Cite news|url=https://www.theverge.com/2018/11/1/18051950/flickr-1000-photo-limit-free-accounts-changes-pro-subscription-smugmug|title=Flickr will end 1TB of free storage and limit free users to 1,000 photos|work=The Verge|access-date=November 1, 2018|archive-date=November 1, 2018|archive-url=https://web.archive.org/web/20181101185808/https://www.theverge.com/2018/11/1/18051950/flickr-1000-photo-limit-free-accounts-changes-pro-subscription-smugmug|url-status=live}}</ref> with the exception of content that was already uploaded with a [[Creative Commons]] [[copyright]] license before November 1, 2018.<ref>{{Cite web|url=http://blog.flickr.net/2018/11/07/the-commons-the-past-is-100-part-of-our-future/|website=blog.flickr.net/|title=The Commons: The Past Is 100% Part of Our Future|date=November 7, 2018|access-date=November 10, 2018|archive-date=December 1, 2018|archive-url=https://web.archive.org/web/20181201173927/http://blog.flickr.net/2018/11/07/the-commons-the-past-is-100-part-of-our-future/|url-status=live}}</ref>

As a result of the [[SmugMug]] buyout, Flickr added the ability for users to download all of their account data, such as photo albums, contacts, and comments.<ref>{{Cite web|last=Fleishman|first=Glenn|date=2019-02-06|title=How to download your Flickr photo library and transfer it to Google Photos or iCloud Photo library|url=https://www.macworld.com/article/3153944/how-to-download-your-flickr-photo-library-and-transfer-it-to-google-photos-or-icloud-photo-library.html|url-status=live|archive-url=https://web.archive.org/web/20190227020452/https://www.macworld.com/article/3153944/how-to-download-your-flickr-photo-library-and-transfer-it-to-google-photos-or-icloud-photo-library.html|archive-date=2019-02-27|access-date=2020-08-29|website=Macworld|language=en}}</ref>

On April 15, 2025, Flickr announced to restrict downloads of original and large-size images (larger than 1024&nbsp;px) owned by free accounts since May 15, Creative Commons-licensed photos and Flickr Commons members will not be affected.<ref>{{Cite web|title=Service Update: Original & Large Size Download Limitations on Free Accounts|url=https://blog.flickr.net/en/2025/04/15/service-update-original-large-size-download-limitations-on-free-accounts/|publisher=Flickr Blog|date=April 15, 2025|access-date=April 27, 2025}}</ref>

===Organization===
The images a photographer uploads to Flickr go into their sequential "photostream", the basis of a Flickr account. All photostreams can be displayed as a justified view, a [[slide show]], a "detail" view or a date stamped archive. Clicking on a photostream image opens it in the interactive "photopage" alongside data, comments and facilities for embedding images on external sites.

Users may label their uploaded images with titles and descriptions, and images may be [[tag (metadata)|tagged]], either by the uploader or by other users, if the uploader permits it. These text components enable computer searching of Flickr. Flickr was an early website to implement [[tag cloud]]s, which were used until 2013, providing access to images tagged with the most popular keywords. Tagging was further revised in the photopage redesign of March 2014. Flickr has been cited as a prime example of effective use of [[folksonomy]].<ref>{{cite web|last=Vander Wal|first=Thomas|author-link=Thomas Vander Wal|title=Folksonomy Research Needs Cleaning Up|date=January 17, 2006|url=http://www.vanderwal.net/random/entrysel.php?blog=1781|access-date=September 4, 2006|archive-date=September 9, 2017|archive-url=https://web.archive.org/web/20170909095704/http://www.vanderwal.net/random/entrysel.php?blog=1781|url-status=live}}</ref>

Users can organize their Flickr photos into "albums" (formerly "sets") which are more flexible than the traditional folder-based method of organizing files, as one photo can belong to one album, many albums, or none at all. Flickr provides code to embed albums into blogs, websites and forums. Flickr albums represent a form of categorical [[metadata]] rather than a physical hierarchy. [[Geotagging]] can be applied to photos in albums,<ref>{{cite web|url=http://www.gossinteractive.com/flickrsets|title=Creating Flickr Sets Video|work=Goss Interactive|date=February 26, 2010|access-date=February 26, 2010|url-status=dead|archive-url=https://web.archive.org/web/20100503085216/http://www.gossinteractive.com/flickrsets|archive-date=May 3, 2010}}</ref> and any albums with geotagging can be related to a map using imapflickr. The resulting map can be embedded in a website.<ref>{{cite web|url=http://www.gossinteractive.com/flickrmap|title=Mapping Flickr Sets Video|work=Goss Interactive|date=February 26, 2010|access-date=February 26, 2010|url-status=dead|archive-url=https://web.archive.org/web/20100503085211/http://www.gossinteractive.com/flickrmap|archive-date=May 3, 2010}}</ref> Flickr albums may be organized into "collections", which can themselves be further organized into higher-order collections.

Organizr is a [[Web application]] for organizing photos within a Flickr account that can be accessed through the Flickr interface. It allows users to modify tags, descriptions and set groupings, and to place photos on a world map (a feature provided in conjunction with [[Yahoo! Maps]]). It uses [[Ajax (programming)|Ajax]] to emulate the look, feel and quick functionality of desktop-based photo-management applications, such as Google's [[Picasa]] and [[F-Spot]]. Users can select and apply changes to multiple photos at a time, as an alternative to the standard Flickr interface for editing.

===Access control===
Flickr provides both private and public image storage. A user uploading an image can set privacy controls that determine who can view the image. A photo can be flagged as either public or private.<ref>{{cite web|url=https://www.flickr.com/help/privacy/|title=Public/Private|work=Flickr|access-date=October 1, 2011|archive-date=December 2, 2020|archive-url=https://web.archive.org/web/20201202091113/https://www.flickr.com/help/privacy|url-status=live}}</ref> Private images are visible by default only to the uploader, but they can also be marked as viewable by friends or family. Privacy settings also can be decided by adding photographs from a user's photostream to a "group pool". If a group is private all the members of that group can see the photo. If a group is public the photo becomes public as well. Flickr also provides a "contact list" which can be used to control image access for a specific set of users in a way similar to that of [[LiveJournal]]. In November 2006, Flickr created a "guest pass" system that allows private photos to be shared with non-Flickr members. This setting allows sets or all photos under a certain privacy category (friends or family) to be shared.<ref>{{cite web|url=https://www.flickr.com/help/guestpass/|title=Guest Pass|work=Flickr|access-date=October 1, 2011|archive-date=November 20, 2015|archive-url=https://web.archive.org/web/20151120010138/https://www.flickr.com/help/guestpass/|url-status=live}}</ref> Many members allow their photos to be viewed by anyone, forming a large collaborative database of categorized photos. By default, other members can leave comments about any image they have permission to view and, in many cases, can add to the list of tags associated with an image.

===Interaction and compatibility===
The core functionality of the site relies on standard [[HTML]] and [[Hypertext Transfer Protocol|HTTP]] features, allowing for wide compatibility among [[Operating system|platforms]] and [[Web browser|browsers]]; Flickr's functionality includes [[RSS]] and [[Atom (Web standard)|Atom]] feeds and an [[application programming interface|API]] that enables independent programmers to expand its services. This includes a large number of third-party [[Greasemonkey]] scripts that enhance and extend the functionality of Flickr. In 2006, Flickr was the second most extended site on userscripts.org.<ref>{{cite web|last=Partington |first=Brian |url=http://www.utata.org/ink/2006/18583.php| title=Ink Interview: Steeev |work=Utata Daily Ink |date=August 19, 2006 |access-date=July 27, 2013| archive-url=https://web.archive.org/web/20060831202653/http://www.utata.org/ink/2006/18583.php| archive-date=August 31, 2006}}</ref> Organizr and most of Flickr's other text-editing and tagging interfaces use [[Ajax (programming)|Ajax]], with which most modern browsers are compliant. Images can be posted to the user's photostream via email attachments, which enables direct uploads from many smartphones and applications. Flickr uses the [[Geo (microformat)|Geo microformat]] on over three million [[geotagging|geotagged]] images.<ref>{{cite web |url=https://techcrunch.com/2006/08/29/flickr-supports-geo-microformat/ |title=Flickr supports "Geo" Microformat |work=[[TechCrunch]] |date=August 29, 2006 |access-date=July 26, 2013 |archive-date=April 27, 2017 |archive-url=https://web.archive.org/web/20170427100832/https://techcrunch.com/2006/08/29/flickr-supports-geo-microformat/ |url-status=live }}</ref>

According to the company, {{as of|2009|8|lc=on}} Flickr is hosted on 62 databases across 124 servers, with about 800,000 user accounts per pair of servers.<ref>{{cite web|url=https://www.flickr.com/help/forum/en-us/100485/page6/#reply672723|title=Bad case of Hiccups!|author=Kevin Collins|work=Flickr.com|date=August 16, 2009|access-date=August 18, 2009|quote=For some of the details, we have 62 DBs across 124 servers- accounts are spread across 2 servers each.

Signed-in Flickr users can "Follow" the Photostreams of other Flickr photographers. Reciprocating this process is optional. A user's homepage contains a stream of their Contacts' photos at 2/3 screen size.<ref name="flickrfaq">{{cite web | url=https://www.flickr.com/help/faq | title=Help | publisher=Flickr | access-date=April 8, 2014 | archive-date=December 2, 2020 | archive-url=https://web.archive.org/web/20201202050152/https://help.flickr.com/ | url-status=live }}</ref>

Groups are another major means of interaction with fellow members of Flickr around common photography interests. A Flickr Group can be started by any Flickr user, who becomes its administrator and can appoint moderators. Groups may either be open access or invitation-only, and most have an associated pool of photos. The administrator of the Flickr group can monitor and set restrictions for the group, assign awards to members, and may curate and organize the photo content. Recent uploads to a group will sometimes appear on its members' homepages. Group photo pools may be displayed in the "Justified View" or as a slideshow.

"Galleries" of photos from other photostreams may be curated by any signed-up Flickr user, provided the feature is not disabled by the photo's uploader, these are then publicly viewable.<ref name="flickrfaq" />

Any Flickr user can post comments to a Flickr photo on its photopage, unless this has been disabled by the uploader, and users can "favorite" a photo. A user's favorites can be viewed in a justified or slideshow display.<ref name="flickrfaq" />

Users of [[Windows Photo Gallery]], Apple's [[iPhoto]] (version 8), Adobe's Lightroom 3.2, Apple's [[Aperture (software)|Aperture]] (version 3.0), [[darktable]], and [[digiKam]] have the ability to upload their photos directly to Flickr. They can also automatically update their status on other [[social network|social networking services]] when they upload their images to Flickr.<ref>{{cite web|url=http://blog.flickr.net/en/2010/06/10/flickr-facebook/|title=Flickr + Facebook!|work=Flickr|date=June 10, 2010|access-date=December 8, 2012|archive-date=December 26, 2012|archive-url=https://web.archive.org/web/20121226043950/http://blog.flickr.net/en/2010/06/10/flickr-facebook|url-status=live}}</ref> Flickr provides a desktop client for [[MacOS|Mac OS X]] and Windows that allows users to upload photos without using the web interface.

Flickr has entered into partnerships with many third parties:

* Flickr had a partnership with the [[Picnik]] online photo-editing application that included a reduced-feature version of Picnik built into Flickr as a default photo editor.<ref>{{cite web|url=http://blog.flickr.net/en/2007/12/05/edit-your-photos-on-flickr/|title=Edit Your Photos!

* In addition to commercial mapping data, Flickr now uses [[OpenStreetMap]] mapping for various cities; this began with Beijing during the run-up to the 2008 Olympic games. {{As of|2008|10}}, this is used for Baghdad, Beijing, Kabul, Sydney and Tokyo.<ref>{{cite web|url=http://blog.flickr.net/en/2008/08/12/around-the-world-and-back-again/|title=Around the World and Back Again|work=Flickr|date=August 12, 2008|access-date=November 7, 2008|archive-date=September 20, 2020|archive-url=https://web.archive.org/web/20200920205913/https://blog.flickr.net/en/2008/08/12/around-the-world-and-back-again/|url-status=live}}</ref><ref>{{cite web|url=http://blog.flickr.net/en/2008/10/30/more-cities/|title=More Cities|work=Flickr|date=October 30, 2008|access-date=November 7, 2008|archive-date=August 6, 2020|archive-url=https://web.archive.org/web/20200806122523/https://blog.flickr.net/en/2008/10/30/more-cities/|url-status=live}}</ref> OpenStreetMap data is collected by volunteers and is available under the [[Open Database License]].

===Filtering===
In March 2007, Flickr added new content filtering controls that let members specify by default what types of images they generally upload (photo, art/illustration, or [[screenshot]]), how "safe" (i.e., unlikely to offend) their images are, and specify that information for specific images individually.<ref>{{cite web |url=https://flickr.com/help/filters/ |title=/ Help / FAQ / Content filters |publisher=Flickr.com |date=March 20, 2007 |access-date=April 4, 2014 |archive-date=December 1, 2020 |archive-url=https://web.archive.org/web/20201201091412/https://help.flickr.com/ |url-status=live }}</ref> Individual images are assigned to one of three categories: "safe", "moderate" and "restricted".<ref name="Wired" /> Users can specify the same criteria when searching for images. The system separates family-friendly photos and adult content; generic image searches normally produce no pornographic results, with the visibility of adult content restricted to users and dedicated Flickr communities who have opted into viewing it.<ref name="Wired">{{cite news|first=Terrence|last=Russell|title=How Porn and Family-Friendly Photos Coexist on Flickr|date=November 7, 2007|work=[[Wired (magazine)#Website|Wired]]|url=https://www.wired.com/techbiz/media/news/2007/07/flickr|access-date=July 24, 2013|archive-date=August 20, 2020|archive-url=https://web.archive.org/web/20200820203548/https://www.wired.com/2007/07/how-porn-and-family-friendly-photos-coexist-on-flickr/|url-status=live}}</ref>

Flickr has used this filtering system to change the level of accessibility to "unsafe" content for entire nations, including [[South Korea]], Hong Kong and Germany. In summer 2007, German users staged a "revolt" over being assigned the user rights of a [[minor (law)|minor]]. {{Crossreference|selfref=no|See {{Section link||Censorship}} below.}}

Flickr offers users the ability to either release their images under certain common usage [[license]]s or label them as "[[all rights reserved]]". The licensing options primarily include the [[Creative Commons]] 2.0 attribution-based and minor content-control licenses – although jurisdiction and version-specific licenses cannot be selected. As with "[[tag (metadata)|tags]]", the site allows easy searching of only those images that fall under a specific license.<ref>{{cite web|title=Flickr: Help: Photos: How can I copyright my photos?|work=Flickr|url=https://www.flickr.com/help/photos/#87|access-date=November 12, 2007|archive-date=March 22, 2016|archive-url=https://web.archive.org/web/20160322054129/https://www.flickr.com/help/photos/#87|url-status=live}}</ref>

On January 16, 2008, Flickr launched a program called "The Commons on Flickr."<ref>{{Cite web |date=2008-01-16 |title=Many hands make light work |url=https://blog.flickr.net/en/2008/01/16/many-hands-make-light-work/ |access-date=2022-08-16 |website=Flickr Blog |language=en |archive-date=July 7, 2022 |archive-url=https://web.archive.org/web/20220707071250/https://blog.flickr.net/en/2008/01/16/many-hands-make-light-work |url-status=live }}</ref> Several international cultural institutions share images using a "no known copyright restrictions" through the program. According to Flickr, the goal of the program is to "firstly show you hidden treasures in the world's public photography archives, and secondly to show how your input and knowledge can help make these collections even richer." Participants include the [[National Museum of Denmark]], [[Powerhouse Museum]], [[George Eastman Museum]], [[Library of Congress]], [[Nationaal Archief]], [[National Archives and Records Administration]], [[National Library of Scotland]], [[State Library of New South Wales]], and [[Smithsonian Institution]].<ref>{{cite web|url=https://www.flickr.com/commons/institutions/|title=The Commons: Participating Institutions|access-date=November 28, 2013|work=Flickr|archive-date=April 21, 2014|archive-url=https://web.archive.org/web/20140421184942/https://www.flickr.com/commons/institutions/|url-status=live}}</ref><ref>{{cite news|first=Noam|last=Cohen|url=https://www.nytimes.com/2009/01/19/technology/internet/19link.html?_r=1&partner=permalink&exprod=permalink|title=Historical Photos in Web Archives Gain Vivid New Lives|quote=In a similar move to harness the public's knowledge about old photographs, the Library of Congress a year ago began adding photographs with no known restrictions to a Flickr service called the Commons.

In May 2009, [[White House]] official photographer [[Pete Souza]] began using Flickr as a conduit for releasing White House photos. The photos were initially posted with a [[Creative Commons license|Creative Commons Attribution]] license requiring that the original photographers be credited. Flickr later created a new license which identified them as "[[Copyright status of works by the federal government of the United States|United States Government Work]]", which does not carry any copyright restrictions.<ref>{{cite journal |last=Singel |first=Ryan |url=https://www.wired.com/epicenter/2009/05/flickr-creates-new-license-for-white-house-photos/ |title=Flickr Creates New License for White House Photos |journal=[[Wired (magazine)#Website|Wired]] |date=May 11, 2009 |access-date=May 21, 2013 |archive-date=May 9, 2012 |archive-url=https://web.archive.org/web/20120509112353/http://www.wired.com/epicenter/2009/05/flickr-creates-new-license-for-white-house-photos |url-status=live }}</ref>

In March 2015, Flickr added the [[Public Domain Mark|Creative Commons Public Domain Mark]] and [[Creative Commons license#Zero / public domain|Creative Commons Zero]] (CC0) to its licensing options.<ref>{{Cite web|url=https://blog.flickr.net/en/2015/03/30/flickr-now-offers-public-domain-and-cc0-designations/|title=Flickr now offers Public Domain and CC0 designations|date=March 30, 2015|access-date=December 3, 2020|archive-date=December 1, 2020|archive-url=https://web.archive.org/web/20201201221807/https://blog.flickr.net/en/2015/03/30/flickr-now-offers-public-domain-and-cc0-designations/|url-status=live}}</ref> The Public Domain Mark is meant for images that are no longer protected by copyright. CC0 is used for works that are still protected by copyright or neighbouring rights, but where the rightsholders choose to waive all those rights.

==Reception==
Flickr became an immediate success and was seen as a successful example of "[[Web 2.0]]", and a year later was purchased by [[Yahoo!]].<ref>{{Cite web|url=http://www.theguardian.com/media/2008/mar/09/web20.internet|title=John Naughton: How Flickr developed into a classic Web 2.0 success|date=March 9, 2008|website=the Guardian|access-date=December 3, 2020|archive-date=October 25, 2020|archive-url=https://web.archive.org/web/20201025222823/https://www.theguardian.com/media/2008/mar/09/web20.internet|url-status=live}}</ref><ref>{{Cite magazine|url=https://time.com/6855/flickr-turns-10-the-rise-fall-and-revival-of-a-photo-sharing-community/|title=Flickr Turns 10: The Rise, Fall and Revival of a Photo-Sharing Community|magazine=Time|access-date=December 3, 2020|archive-date=November 27, 2020|archive-url=https://web.archive.org/web/20201127014136/https://time.com/6855/flickr-turns-10-the-rise-fall-and-revival-of-a-photo-sharing-community/|url-status=live}}</ref> Initially, the site was most popular with professional photographers and graphic designers as well as [[blog|bloggers]] who used it as an image repository.

==Controversies==
===Censorship===
On June 12, 2007, in the wake of the rollout of localized language versions of the site, Flickr implemented a user-side rating system for filtering out potentially controversial photos. Simultaneously, users with accounts registered with Yahoo! subsidiaries in Germany, Singapore, Hong Kong, and Korea were prevented from viewing photos rated "moderate" or "restricted" on the three-part scale used. Many Flickr users, particularly in Germany, protested against the new restrictions, claiming unwanted censorship from Flickr and Yahoo.<ref>{{cite web| url=http://www.heise.de/english/newsticker/news/91160| work=[[C't]]| title=Flickr Filter Raises Eyebrows| last=Morris| first=Craig| date=June 14, 2007| archive-url=https://web.archive.org/web/20070630132833/http://www.heise.de/english/newsticker/news/91160| archive-date=June 30, 2007| access-date=July 24, 2013}}</ref>

Flickr management, unwilling to go into legal details, implied that the reason for the stringent filtering was the existence of some particularly strict age-verification laws in Germany. The issue received attention in the German national media, especially in online publications. Initial reports indicated that Flickr's action was a sensible, if unattractive, precaution against prosecution,<ref>{{cite web|url=http://www.spiegel.de/netzwelt/web/0,1518,488542,00.html|title=Zwangsfilter: Flickr verbietet Deutschen Nacktfotos|work=[[Spiegel Online]]|last=Lischka|first=Konrad|date=June 14, 2007|access-date=May 21, 2013|archive-date=May 4, 2012|archive-url=https://web.archive.org/web/20120504155407/http://www.spiegel.de/netzwelt/web/0,1518,488542,00.html|url-status=live}}</ref> although later coverage implied that Flickr's action may have been unnecessarily strict.<ref>{{cite web|url=http://www.spiegel.de/netzwelt/web/0,1518,489837,00.html|title=Foto-Portal: Jugendschützer: Flickr-Filter nach deutschem Recht nicht nötig|last=Lischka|first=Konrad|date=June 21, 2007|work=[[Spiegel Online]]|access-date=July 24, 2013|archive-date=May 4, 2012|archive-url=https://web.archive.org/web/20120504161512/http://www.spiegel.de/netzwelt/web/0,1518,489837,00.html|url-status=live}}</ref> On June 20, 2007, Flickr reacted by granting German users access to "moderate" (but not "restricted") images, and hinted at a future solution for Germany, involving advanced age-verification procedures.

Under OCILLA, a service provider such as Flickr is obliged to delete or disable access to content as soon as they receive an official notice of infringement, to maintain protection from liability.<ref>{{cite web|url=http://www.copyright.gov/title17/92chap5.html#512|title=U.S. Copyright Office – Copyright Law: Chapter 5|publisher=Copyright.gov|access-date=March 18, 2013|archive-date=March 27, 2021|archive-url=https://web.archive.org/web/20210327133232/https://www.copyright.gov/title17/92chap5.html#512|url-status=live}}</ref> After having one of his own pictures taken down following an incorrect DMCA claim, British comedian [[Dave Gorman]] researched the issue and concluded that if the Flickr user was not based in the United States or they were, but the person filing the notice of infringement was not, Flickr deleted the disputed content immediately.

In 2019, Flickr added new theft detection tool options to certain users. Some subscribers will be provided "copy-protection tools that can detect if their images have been used without permission," the BBC reported in 2019, noting "Flickr Pro subscribers will be able to monitor up to 1,000 images and send automated copyright claims to people or companies that use their photos."<ref>{{Cite news|url=https://www.bbc.com/news/technology-47852150|title=Flickr adds photo theft detection tools|last=Fox|first=Chris|date=2019-04-09|access-date=2019-04-30|language=en-GB|archive-date=November 12, 2020|archive-url=https://web.archive.org/web/20201112165802/https://www.bbc.com/news/technology-47852150|url-status=live}}</ref>

===Sale of Creative Commons-licensed photos===
In November 2014, Flickr announced that it would sell wall-sized prints of photos from the service that are licensed under Creative Commons licenses allowing commercial use. Although its use of the photos in this manner is legal and allowed under the licenses, Flickr was criticized by users for what they perceived to be unfair exploitation of artists' works, as all the profits from these offerings go to Yahoo! and are not shared with their respective photographers, and users were not given a means of opting-out from the program without placing their photos under a more restrictive non-commercial license. By contrast, a similar opt-in program for "licensed" photos does give photographers a 51% share of sales. On December 19, 2014, Flickr General Manager Bernardo Hernandez announced they would pull all Creative Commons-licensed images from the program and issue refunds, stating that "Subsequently, we'll work closely with Creative Commons to come back with programs that align better with our community values."<ref name="guardian-flickrccsale">{{cite news|title=Flickr scraps plan to sell users' photos as wall art after licensing row|url=https://www.theguardian.com/technology/2014/dec/19/flickr-creative-commons-wall-art-licensing-row|access-date=December 22, 2014|work=The Guardian|date=December 19, 2014|archive-date=November 12, 2020|archive-url=https://web.archive.org/web/20201112001847/http://www.theguardian.com/technology/2014/dec/19/flickr-creative-commons-wall-art-licensing-row|url-status=live}}</ref><ref name="guardian-flak">{{cite news|title=Flickr takes flak for selling Creative Commons photos as wall-art prints|url=https://www.theguardian.com/technology/2014/dec/02/flickr-creative-commons-photos-wall-art|access-date=December 22, 2014|work=The Guardian|date=December 2, 2014|archive-date=November 12, 2020|archive-url=https://web.archive.org/web/20201112024725/https://www.theguardian.com/technology/2014/dec/02/flickr-creative-commons-photos-wall-art|url-status=live}}</ref><ref>{{Cite web|url = https://blog.flickr.net/en/2014/12/18/an-update-on-flickr-wall-art|title = An Update on Flickr Wall Art|date = December 18, 2014|access-date = April 8, 2015|website = blog.flickr.net/|archive-date = December 2, 2020|archive-url = https://web.archive.org/web/20201202002955/https://blog.flickr.net/en/2014/12/18/an-update-on-flickr-wall-art/|url-status = live}}</ref>

On November 1, 2018, Flickr announced new restrictions for its users.<ref>{{cite news|url=https://www.businesswire.com/news/home/20181101005328/en/Flickr-Announces-New-Photographer-Centric-Improvements-Flickr-Pro|title=Flickr Announces New Photographer-Centric Improvements to Flickr Pro, Free Plans|work=BusinessWire|date=November 1, 2018|access-date=February 23, 2019|archive-date=November 27, 2020|archive-url=https://web.archive.org/web/20201127190923/https://www.businesswire.com/news/home/20181101005328/en/Flickr-Announces-New-Photographer-Centric-Improvements-Flickr-Pro|url-status=live}}</ref>
*On January 8, 2019, non-paying users would only able to upload up to 1000 files free of charge.
*Deletion of the oldest files, determined by the upload date, was scheduled to begin on March 12, 2019, until the limit of 1000 files was met. The size of the individual files would not be relevant. Alternatively, users could upgrade to Pro subscription for US$60 per year.<ref>{{cite news|last1=Stadlen|first1=Andrew|title=[Official Thread] Timeline extension for free Flickr accounts over 1,000 photos + videos|date=2019-02-06|work=Flickr|url=https://www.flickr.com/help/forum/en-us/72157676293604137/|access-date=2022-04-02|archive-date=April 3, 2022|archive-url=https://web.archive.org/web/20220403062437/https://www.flickr.com/help/forum/en-us/72157676293604137/|url-status=live}}</ref>
On March 17, 2022, Flickr revealed that it had not in fact deleted any photos for exceeding storage limits. However, it announced that it would soon implement a policy limiting the sharing of "moderate" or "restricted" content to Pro users, and limiting free users to 50 "non-public" images. Images beyond these limits would be at risk for deletion.<ref name=FlickrForever/>
