Quite.  It would be fairly trivial to back the graphic with an
imagemap.  After a little research I suspect that PNG might be a much
better way to go.  It doesn't have the patent questions that GIF has,
and looks to be both smaller/more efficient sa well as a more direct
translation from his storage formats.
