What are the dimensions of the images in pixels, hughie? Are they all the same size?
This is an excellent question, and may take you directly to a Norton issue, especially their ad blocker, which can cause all kinds of problems with rendering images, but not necessarily predictably, and only for a very few users. It about drove me crazy the first time that I encountered it. (Of course, WebmasterWorld came to my rescue on that one as well.) Most often it seems to come down to the ad blocker.

When you see this kind of problem, Norton Internet Security's stupid (in all senses of the word) ad-blocker is to blame in almost all cases. It is my number one question when someone complains about a problem with one of my sites.
