When all or part of an image source is unknown or unknowable, use these points to guide your MLA image caption:
Unknown Artist, Author or Creator
List that source by title in your works cited list. The title should be followed by the name of the source in the citation, and the remainder of the citation composed as appropriate for the source type. Alphabetize reference list entries beginning with a title using the primary word of the title (excluding a, an, or the).
An Image without a Title
If an image is not titled, create a brief, descriptive title for it. Do not italicize this title or place it in quotes, and capitalize only the first word and any proper nouns.
Use "n.d." (for "no date") in the appropriate place in your citation. When this is used after a period in a citation, capitalize the "n" ("N.d.").
