Help with Menu

I’m trying to emulate the menu on this site:

http://www.bobmcnamara.com

Click on either the insdie or outside for the image gallery. I want to create the menu that hides and exposes itself like that one. I’ve tried something like this adapting VoetsJoeba’s flashlevel scroller, but have not been successful at having my image thumbnails load the larger image with the reusable MC loader. Also, my menu glitches when it hides and exposes as you roll over each thumbnails.

PLEASE HELP!
