After a little more thought, the idea of committing to this API isn't as
bad as I had initially thought. Functions like add-to-list do it. After
all, this function is supposed to set things up so the preferred images
are used, and that's done by putting the image directory first in the
path.

Unless I hear an objection this morning, I'll go ahead and make that
change (document that the image directory comes first and update the
example per Rainer's note). I'll also check it into image.el and send
out a note to emacs-devel about it (unless someone thinks I should send
a note to emacs-devel beforehand).
