What is Wikimedia Commons?Edit
The aim of Wikimedia Commons is to provide a media file repository "that makes available public domain and freely-licensed educational media content to all, and that acts as a common repository for the various projects of the Wikimedia Foundation."
Wikimedia Commons is a multilingual project. The default language is English, but registered users can customize their interface to any other available user interface translations. Many pages have also been translated into various languages. Users are encouraged to help with translations.
Central media repositoryEdit
Formerly each of the many Wikimedia projects—every single Wikipedia and Wiktionary, as well as Wikibooks, Wikisource, Wikinews, Wikiversity, and Wikiquote—used their own image namespace. There was no reliable way to reference images on other projects. Many good, free uploads on one wiki could go unnoticed on another. Thus, there was needless duplication of intellectual and creative work, as well as unnecessary redundancy and increased maintenance.
