Mozilla is blocking images form other servers than the HTML came from

Hi,
   Mozilla 1.2b does not even load images that do not come from the same 
server that the HTML file does come from. Now my most loved web forum 
does use multiple servers,, one specifically for images, and I cant use 
it's functionality anymore because most buttons are images wich don't 
get loaded and everything is absolutely not nice.

   Ok, enough of that. How can I allow the loading of remote images fpr 
specified sites? Or disable this feature alltogeher?

thanks,

mfg
