The Wikimedia Foundation owns almost none of the content on Wikimedia sites — it is owned by the individual creators. However, almost all may be freely reused without individual permission according to the terms of the particular license under which it was contributed to the project, but some licenses may require that the original creator be attributed. You do not need to obtain a specific statement of permission from the licensor (unless you wish to use the work under different terms than the license stated).

While the copyright and licensing information supplied for each image is believed to be accurate, the Wikimedia Foundation does not provide any warranty regarding the copyright status or correctness of licensing terms. If you decide to reuse files from Commons, you should make your own determination of the copyright status of each image just as you would when obtaining images from other sources.

Other restrictions may apply. These may include trademarks, patents, personality rights, moral rights, privacy rights, or any of the many other legal causes which are independent of copyright and vary greatly by jurisdiction.
