image is wacky

[csli820]

hi, i created an rollover image (a sitemap image) in fireworks and exported into dreameweaver for the web. (it's javascript) somehow when the image is uploaded, the alignment is all off. is it because of the generated coding? i tried to debug the code myself but i don't seem to find a solution.

here's the url:

It seems fine to me.
Has something changed?
What browser are you using?
