Cant center my slideshow... PLEASE help!

[newbieweb]

Im getting near the end of designing my first website and I am unable to figure out how to center this one thing. I have had another web person try to help but none of her suggestions worked.

If you are willing to help me, please look at the code on my page
http://www.heatherandderrick.com/album2.htm

My site is built at 760 pixels, and does not alter to fit the browser window. its set to stay as is, but it looks like my slideshow might be set to alter with the browser, but i want it to just stay centered under the text "photo album"

Please let me know if you can help me, Id really appreciate it!

thanks,
heather
