Figures in a paper require a number, title, and note with copyright attribution. For presentations, the number and title are optional, but the note with copyright attribution is still required (with a few exceptions). They should also have a reference list entry.
The figure note contains information or comment on the figure (optional), and a copyright attribution.
Copyright attribution includes title, author, date, site name (if available), and location (URL), as well as information about the copyright and permission status (if necessary) of the item. It is used instead of an in-text citation.
