I have just had someone customise my Copperplate gallery into my site and it looks fine in the admin in IE(6) however, if I go to user mode, I see this:

But, if I use Mozilla Firebird instead of IE, it looks fine - http://www.mytton.net/firebird.jpg

I can't find what is causing this Any suggestions?
