This looks like a great site. I'm evaluating different options right now for a photography shop, and one of they key requirements for them is the ability for a customer to upload an image, and then make changes to the image with a live preview. E.g., add a border, change it from full color to b&w or sepia, rotate it, add and position text, etc.

Has anybody tried this sort of thing with Ubercart? Is it even feasible?

Thanks for any feedback!
