Copyright Basics

Remember that you do not need permission if you are using something that is not copyrightable or is in the public domain, or if you are using it in a way that does not implicate one of the rights of copyright holders or is permitted by a user’s right. For more information on these topics, please consult Copyright Basics.

Reverse Image Searches

Because images are so often published without attribution, it can be especially difficult to locate their copyright holders. If you have an image you would like to license but need to identify and contact the copyright holder, a reverse image search engine may be helpful. You can use a reverse image search engine to find out where an image came from, where it is being used, and whether higher resolution or modified versions of the image exist.
