Wikimedia Commons uses the same wiki-technology as Wikipedia and thus everyone can edit it easily and without advanced technical skills directly in the web browser.

Unlike traditional media repositories Wikimedia Commons is free. Everyone is allowed to copy, use and modify any files here freely as long the source and the authors are credited and as long you release your copies/improvements under the same freedom to others. The Wikimedia Commons database itself and the texts in it are licensed under the GNU Free Documentation License. The license conditions of each individual media file can be found on their description pages.

Contribute your work

If you're a good photographer don't hesitate to contribute your valuable images, if you're a good musician or film/theater artist do not hesitate to publish your own records of your performances of free pieces here.
