Generally, you have to use strict filters (-*), and 
then accept what you want to: (example)
-* +www.mysite.com/myfolder/mypage.php* +*.jpg +*.gif
(For example, if images are located in "foobar.php" 
pages, use +*foobar.php* additional filters.)

Ensure that you defined limited number of connection, 
however (example: 2 simultaneous connections), image 
websites are oftenly clobbered by abusing people, and 
are then forced to 'ban' offline browsers.
