Dreamweaver to Firefox issue =(

[Cyberartist26]

Hello everyone how are you? =),:yawn:

I am having some trouble with some pictures on a website =(
recently i made a website using photoshop cs4, sliced it up and sent straight to dreamweaver cs4.

here is my client's website -

http://www.hollomanlaw.org/home.html

it looks good with Internet Explorer 7 but when i access it with Firefox 3.0 the whole thing looks scrambled =(

I mean, a segment of a picture would be way over to the right while another piece is shifted to "way over yonder":eek: :confused:

Any help is greatly appreciated and thank you for your time =) :p:D
