Maybe I'm an idiot and it's been there all this time, but I've just noticed the slideshow method of displaying either your gallery or favorites (just one per customer ;)) I like that it can pan through the image and you can even go full screen. Since most of my collages are pretty big, pixelwise, it can act as a teaser for what the image looks like.
I think it's pretty cool, what do you think? Just wish it had a random order option.
