Flash / XML gallery thumbnail problem

I’ve come across a problem that we can not seem to find any solution to. We’re trying to update our firms site with XML and Flash and would like our gallery/portfolio to have dynamic thumbnails instead of the generic boxes that XML generates. here is a link for a screen shot of what we are hoping to accomplish.

The second link is a test site of where we currently are stuck.

The thumbnails change on rollover from black and white to color. We have 2 folders with the on and off images saved with the same names.

Anyone that can help will be our #1 super friend forever. If it’d be helpful to see the current coding of where we are at now let me know and I’ll post it too. Thanks!
