Wikimedia Foundation, who kindly hosts MediaWiki.org, takes copyright law very seriously. File description pages are tagged with the license and the source of the file. This makes it as easy as possible for readers, Wikimedians, and creators of derivative works to know what they can and can't do with the files on this wiki.
