The only problem I see is with transformed images being cached, and
then the client rerequesting the image without going to the page
that generates the image.

If this is a problem then you should make the transformed images
dynamically generated, but I doubt this matters at all.

I would make sure to do something like

	foo/images/bah.jpg # original
	foo/transformed/bah.jpg

and not

	foo/images/bah.jpg
	foo/images/bah.transformed.jpg

since it's easier to delete the transformed images this way.

Good luck =)
