Gallery Skimming!

[GM]

OK! I need help! the follwoing script is used for random link:

<?php
$fileName = "./name.txt";
mt_srand( (double) microtime() * 1000000 );
$a = file($fileName);
$randNum = mt_rand( 0, sizeof($a)-1 );
header( "Location: ". $a[$randNum] );
?>

And it works great now i want to add gallery skimming option so that i may send some hits to blind link sponsors how can i do that?

Greenguy, Jim anyone???
