Icons missing

Hi,

I installed the widget as told in the “installation” section.
So far ist is properly working but ist does′nt display the Icons, only the channel-names and the Usernames so now it looks more like a messy list than an good widget.
The images are extracted completely and none of them is damaged (via FTP i can view them all).
but they are′nt displayed….

Hope sb can help me with this problem ??
