I can limit the size.. But then I have to limit to the lowest screen size. Like my laptop that I'm on now.. So if your on a bigger monitor, you get hosed.

The good thing about thumbnails is it'll show as big as possible for you.. While not breaking the layout of the screen..

These are really well done lightboxes, and I don't think anyone would have issues with them as far as popups, etc.
