But in the case of the zip I downloaded, there are lots of files, in
several directories.  It wasn't clear to me, at least, which of those
are "these libraries", so it wasn't clear which directories to add to
PATH.

Ideal would, I think, be something in the Emacs manual.  Displaying
images should not be something that users need to hunt for how to do.
