  • MaxPixel

    Like the web sites above, MaxPixel hosts images that are free and unrestricted, even for commercial use. However, some of the images require an attribution caption. Be sure to check the license terms on the right side of each page displaying an image.

  • Flickr - Creative Commons Licensed & Public Domain Works

    Please proceed with caution when browsing the Flickr web site. Flickr hosts a variety of photographs, but some of them are copyright protected and highly restricted, so please review the license terms before using any photograph or image from Flickr. To help you with this process, we are providing the link above, which is to a special page on Flickr that provides a jump-off point for access to all the Creative Commons licensed and public domain works on their site. If you follow the above link and click one of the "see more" links, it will then give you an option to search images which are licensed or unlicensed according to that group.

  • PublicDomainVectors (Clip Art)

    This web site offers clip art that is completely unrestricted in use.

  • Smithsonian Institution — Public Domain Images

    Via Flickr Commons. Please note that most other photographs are copyright restricted, which is why that particular site is not listed here. Before using photos from any other Flickr contributors, please first carefully read its licensing terms.

  • New York Times — Public Domain Images Archives

    Via Wikimedia Commons

  • National Gallery of Art

    The NGA has an open access policy for digital images of works of art believed to be in the public domain. Images are free of charge for any use, and users do not need to seek permission.

  • The British Library

    Over a million images on Flickr Commons for anyone to use.

  • Wellcome Images Library

    Over 100,000 high-resolution historical images including manuscripts, paintings, etchings, early photography, and advertisements are freely available under the Creative Commons Attribution (CC-BY) licence, with an acknowledgment of the original source.

  • Wikimedia Commons

    Please use Wikimedia Commons with caution. Since the public contributes to a wiki with minimal editorial oversight, many of the millions of media contained within are licensed under a variety of licenses (most commonly CC BY-SA).  At times, contributors also make unauthorized uploads of media copyrighted by third parties. It can still be a useful resource, but due diligence in verifying the original authorship of an image by performing a reverse image search is always a good idea.
