Abstract The question is examined of how pictures are to be individuated from other kinds of respresentations. This is discussed in relation to the classic treatment by Goodman, and a further development by Schier. Neither of these is found satisfactory. It is argued that the issue should be seen as interest-relative, and that in formal terms a version of a theory based on structure mapping is the most promising candidate.
