Wikimedia Commons

Wikimedia Commons provides images and other files, with individual file pages explaining source information and the licence conditions relevant to potential reuse.

It is useful for investigating a term, subject or reference question. Its focus includes Media repository, Image discovery and Reuse information, helping a visitor identify what kind of answer or source the service provides and where the original material needs to be read in context.

The official Wikimedia Commons site includes sections for Images, Videos and Mathematics.
