Using images can be complicated! What determines whether or not the use of an image is fair and permissible? Copyright, fair use, public domain, Creative Commons licenses, attribution, open access, permissions, credit, and citation come into play. Sometimes permitted use guidelines are not clear cut. In general, purely educational uses of images are permitted, but, if in doubt, check New York University Libraries' Copyright: Using Images. Remember that every image used needs to be cited or attributed with its creator and URL or other source provided. This Guide highlights links to general and image-specific websites that offer clearly-written usage definitions and provide sample applications of copyright and fair use guidelines.
