I really don't think this is a template issue because when I changed to classic green, it still did the same thing. I do however think it is related to firefox, or the browser I am using. I tried the site on internet explorer recently and the images displayed perfect every time. But Firefox there is still a problem. I am yet to try other browsers but I think this is the issue. If that is the case, I still have no idea what to do to fix the problem though!
