dreamweaver-website on cd for pac AND mac - i need help!

hello!
i made a website with dreamweaver 4.0 and burned it on cd. at my pc its working fine, the mac also took the cd without problems, it shows all stuff on the cd, but if you dubbleklick the index.htm it dont show the pictures and the background. only the written texts are shown. why? and how can i change it?
i burned the cd in the ISO-norm, so both plattforms can read the cd.
i also changed all ordners, names and links in capitalform (was a tip from a macianer), but it didnt change anything... please give me some help....
