Citing Artwork in Chicago Style
When using images, make sure you cite them properly. All images used in research papers and presentations need to be cited -- even open access and creative commons images found online.
Artwork used to illustrate a research paper needs to be labeled and numbered as Figure 1., Figure 2., and so on.
Caption should include: artist's name, title of work (italicized), date, medium, measurements, and museum, archive, collection, or gallery which holds the work.
Under the caption, cite your source: the book, article, or website the image came from. Cite the source as if it were a full source in a footnote, including the page and figure numbers from the original. Be sure to include the URL and date accessed if your source is online.
