If your use falls under Fair Use, copyright doesn’t matter. It may be polite to inform the repository of your use, but it’s not legally required that you consult them.
Is it an image or a “slavish” (identical, basically just a copy) reproduction that hasn’t been altered?
Was it published in the US pre-1923? Maybe in a newspaper or book of photographs?
Yes to both? Public domain. No one can claim rights over it.
Did you get your image from a library-licensed resource (e.g., ARTstor)? If so, scholarly use (including publication) is included in our licensing agreements for these resources.
If you are unclear about copyright or fair use for an image, ask a librarian!
Whether fair use or public domain apply, it’s usually best for good relations to let rightsholders or the relevant repository (in the case of ARTstor this would be the library or archive, not ARTstor) know of your intended use unless they indicate other preferences in their policy statement.
