  • 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, which is not compliant).  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.
