Documenting sources for images can be challenging. Consult the most current style manual in your disciple. You may also want to consult with your instructor.
When using an image in a paper or project, make sure to cite where you found the image. Even if images are in the public domain or allowed to be reproduced for research, teaching and private study without prior permission, most still require that the owning repository be properly credited. Any other uses, such as inclusion in a publication or other media project, require permission from the copyright holder and the owning repository. (See copyright tab)
