Wikimedia Commons (or simply Commons ) is an online repository of free-use images, sound, and other media files.  It is a project of the Wikimedia Foundation .
Files from Wikimedia Commons can be used across all Wikimedia projects  in all languages, Including Wikipedia , Wikibooks , Wikivoyage , Wikispecies , Wikisource , and Wikinews , or downloaded for offsite use. The repository contains over 40 million media files.  In July 2013, the number of edicts on Commons reached 100,000,000. 
The project was proposed by Erik Möller in March 2004  and launched on September 7, 2004.   A key motivation behind the setup of a central repository was the desire to reduce duplication of effort across the Wikimedia projects and Languages, as the same file had to be uploaded to many different wikis separately before Commons was created.
The aim of the Wikimedia Foundation is to provide a common repository for the various projects of the Wikimedia Foundation. The expression “educational” is to be understood according to its broad meaning of “providing knowledge, instructional or informative”. 
Most Wikimedia projects still allow local uploads qui are not visible to other projects or languages, aim this option is Meant to Be used Primarily for material (Such as fair usecontent) qui local project policies allow, goal Which would not be permitted selon the Copyright policy of Commons.

The default language for Commons is English, but registered users can customize their interface to any other available user interface translations. Many content pages, in particular policy pages and portals, have also been translated into various languages. Files on Wikimedia Commons are categorized using MediaWiki’s category system. In addition, they are often collected on individual topical gallery pages. While the project was originally proposed to also contain free text files, Wikisource continues to be hosted on a sister project .
The site has been criticized for hosting large amounts of amateur pornography, which are often uploaded by exhibitionists who exploit the site for personal gratification, and who are enabled by sympathetic administrators.  In 2012, BuzzFeed Wikimedia Commons as “littered with dicks”. 
In 2010, Wikipedia co-founder Larry Sanger reported Wikimedia Commons to the FBI . After This Was Reported in the media, Jimmy Wales , founder of the Wikimedia Foundation qui hosts Commons, used His administrator status to delete Several images without debate from the Commons community. Wales responded to the backlash from the community by voluntarily relinquishing some privileges, including the ability to delete files. 
Wikimedia Commons Wikimedia Commons has been archived on the Web. Daniel Kinzler The author of the article “Common Understanding”, which describes the use of the Wikipedia project (“CheckUsage”), Such as deletions to the relevant wikis (” CommonsTicker “).
Specialized uploading tools and scripts such as ” Commonist ” have been created to simplify the process of uploading large numbers of files. In order to review free happy pictures uploaded to Flickr , users can Participate in a defunct collaborative external review process ( ” FlickrLickr “) qui HAS resulted in more than 10,000 uploads to Commons.

The site has three mechanisms for recognizing quality works. One is known as ” Featured pictures “, where they are nominated and nominated. This process started in November 2004. Another process known as ” Quality images ” began in June 2006, and has a simpler nomination process comparable to “Featured pictures”. “Quality images” only accepted works created by Wikimedia users, “Featured pictures” by NASA. A third image assessment project, known as ” Valued images “, started on June 1, 2008 with the purpose of recognizing “the most valued illustration of its kind”
The three mentioned processes have a small share (less than 0.1%) from the total number of files. However, we have not found any results in this section. Generally, Commons is not a competition but a collection; A quality of the description and organization of files and their descriptive and informational. Files with specific defects can be tagged for improvement and warning or even proposed for deletion.
The site held its inaugural “Picture of the Year” competition, for 2006. All images that were made a Featured picture during 2006 were eligible, and voted on by Wikimedia . The Aurora Borealis over snowlands, taken by an airman from the US Air Force . The competition has become an annual event.
