Emmanuelle, I think it's a gorgeous site and I would list it in a heartbeat. (Hint, hint.)
I don't personally reject sites based on image size, but I kind of understand where DD is coming from. Of course I can't speak for him, but from my point of view, (1) large images are a waste of your bandwidth, and indicative of serious newbieness (I know this is not the case where you're concerned) and (2) More important - make 'em pay for high-quality images. Free sites should give a preview, not the full product.
My 2 bits.
