I can't see your image gallery. All I see when I load that link is a white rectangle swf stage, but there is nothing in it, just blank white.
I think the link you're trying to direct us to is:
http://www.mattsfolio.com/jamiewhite/
Hmm, when you implemented the slideshow onto your stage, did you center it to the stage (aka that big white space). That would be my suggestion if your editing your fla files get them to integrate into your current flash webpage.
About the "?" :
