Hey!
Could you possibly show the gallery? So I could see what is the problem there. :)
Usually these kind of problems are quite easy to fix, but obviously the original flash file & its code affects a lot onto the problem.
If you can PM me and describe the problem better or possibly show the swf (or even fla), it would be great and I could tell you straight away if I can fix it and how hard it is to fix.
BR,
