Make browsing photos quicker and easier. Having to load a page for every photo is very slow.
I would say make browsing photos similar to FB where you can switch photo to photo rather quicky.

Your talking about lightbox. Agreed that this would be a great addition for SummitPost. However many hate the idea of being forced to use it. So I propose some sort of lightbox option or button. This way both parties get what they want.
