Copyright & Royalties
If you're using one or more images in a paper, report, article, or other publication, you'll need to make sure you're avoiding copyright infringement. You can do so in one of two ways:
- Pay for the images.
- Use images that are royalty-free.
If an image meets one or more of the following criteria, it is royalty-free:
- Created by the U.S federal government.
- In the public domain (first copyrighted in the US prior to 1925) are not subject to copyright law and can be used by others. View Cornell University's "Copyright Term and the Public Domain in the United States" chart for more detailed information about the public domain.
- Subject to creative commons licenses (details below).
Even if an image is royalty-free, you may still need to abide by certain stipulations like attribution, depending on the image's terms of use.
