I don't see any image map... where's it supposed to be?
On a slightly different tack...
Your body margin is too big (10em). I'd have it at just 2 or 3em. I have a widescreen computer and with sich a big top margin and big logo (too big for my liking), each time I click a link and get a refreshed page, I have the annoying task of scrolling down to see product info. After 2 or 3 refreshes, I just want to shop elsewhere...
I believe header logos should be small - no taller than 75 - 90 pix - so that customers can see what they've come for... PRODUCTS.
Just my opinion...
