Can this be done with Flash Gallery?

Issue Summary

I like this module and I have no problem paying for the pro version provided this can be done. I don't know about this stuff, so I have to ask if it would be possible.

Using the watermark Module, would it be possible to have uploaded photos watermarked before they get all nice and "flashy"?
Would it be possible to allow for people to comment on each photograph as well as rate photos, perhaps using AJAX star system, but only allowing people logged into the site to do these things?

Simple enough question, but I don't know how easy it would be, if at all possible to do the comments with the flash images considering how quickly the images change. Would this be more easily done with Gallery2? Thanks a ton.
