Problem with Gallery component in Mambo

When using the Gallery component in Mambo - the images/titles don't display properly in Firefox. It's a bit better in IE but I still don't get my template formatting. you can see it at www.allmyvoices.com and selecting "test gallery" in the menu. The "photo gallery" link show how it should look (that's done with a wrapper). Any help in fixing this would be appreciated.

I have already rued out the template being the problem since the results are always the same no matter which template I use.

Thanks Mario
