As far as I know you have 2 options.. You
can get a program like auto gallery pro.. It
will create a seperate page for your different links.. or what I did once was
get a simple random link script found at:
<a target=new href="http://www.worldwidemart.com/scripts/">
http://www.worldwidemart.com/scripts/</A>
It pulls the links at random from a database.. I just created a seperate database for each category and used it in conjuction with my trade script...
worked rather well..
