yes, put this:
<?
$gals=File("babes.txt"); 
SRand((double)Microtime()*1e6); 
$n=rand(0,count($gals)); 
Header ("Location: $gals[$n]"); 
?>

to "babe.php3" file and create "babes.txt" ... each URL on new line:

http://ultra-babes.com/cmpg48/smt.html
http://www.hadesporn.com/pussy/claudia/index03.htm
..
..

and do the same with all your caategories:

teen.php3 ..
<?
$gals=File("teens.txt"); 
SRand((double)Microtime()*1e6); 
$n=rand(0,count($gals)); 
Header ("Location: $gals[$n]"); 
?>

teens.txt:

gallery URL 1
gallery URL 2
..
gallery URL N

etc.

hope that helps
