Touch? Photoswipe? Big images & zooming

Hello there, I’m looking to create a very simple site, perhaps to be run as a Kiosk on a standalone machine most of the time (with touch screen), that handles fairly big image files that can be fairly deeply zoomed into. I am looking at TF Touch. Does that seem like a wise choice? Any other words of wisdom?
I have nearly no budget, almost no time, and weak skills. What can go wrong?
