Well i did get that part now...That the reason why i've included a link to a tarball (.rar file) where the site is as-is. Including the images, css and html that is used to that one site only. The problem is...that i don't know where to search the cause of the problem. If i had the problem i could rather fix it and i didn't need these forums here, right?
I don't use absolute links. In HTML i use links like "./img/" in the img src tags and in css as /img/.
Downloading/installing a pseudo server isn't needed because i open the links in firefox it self (open file, works great because it's HTML).
