Ah! That's what's happening... I just noticed that my local webserver
delivers broken images (i.e. only a part of them), but because I'm busy
with other stuff atm, i didn't care to find out what's happening.

Some details:

Kernel
------

Apache
------
Server version: Apache/2.0.54
Server built: Nov 19 2005 22:05:20

FS
