You know.. I've been thinking about this thread, interesting topic

One thing that might be a consideration, if the surfer realises that a thumb isn't the same as the big picture, it might make him look at more of them, which could be bad bandwidth wise. Myself, I like to use good size thumbs, at least 110 x 110 or more so the image can be seen well. This way, if there's a picture they don't want to see, they know that and won't click on the larger image. When you're talking about getting a lot of hits to a gallery, that bandwidth can really add up
