Hi, was messing around with this one
http://www.collectors-info.com/testing/ro.html if its any good for you? let us know. I am not very good with layouts so you may have to get somone to help you on this. But if you want all the images under the main one? then its no problem.
The info part on click can be taken out if not wanted with no problem.
Not sure if it works in all browsers yet, but give it a try.
PS. This is not flash.
