As an end user for IBY, when I make my 4 selections for something like a "4 digital images" product, I'd like to see the images that I've already selected indicated in some way (so I don't select the same image twice). This is even more of an issue when selecting images for a large package. I can't keep straight which images I've already selected... a big issue for my subject matter where there are many similars and I'm moreover using a fairly aggressive watermark.
