Preview Tool

We use a basic image preview tool where I work to discuss and present designs, it's super useful but pretty rudimentary. I've often thought about how my dream image preview tool would look and thought I would design a basic one to help hone my UI design skills. There's little chance this would ever get build but it was fun to design.
