Bummer, but that justifies having the different class, so that's fine.

Yeah, we have to be able to detect the images properly (the patch won't
pass unit tests if not). There is an image in the tree for the older
one, if you want to take a look in there. Also, the users mailing list
is a good way to grab a bunch of sample images if you're willing to
survey them.
Thanks!
