Could easily be done with some php code, especially if its text links etc.
Let me provide something simple although this isnt tested but should work
PHP Code:
<?php
// FILE TO PULL FROM
$links_file = "amateur.txt";
$links = join('', file($links_file));
$alllinks = split("\n", $links);
$random_link = rand(0,count($alllinks));
list($link,$desc) = split("\|", $alllinks[$random_link]);
echo '<a href="'.$link.'" target="_blank">'.$desc.'</a>';
?>
Then in amateur.txt have a link|desc one per line something like:
http://www.url1.com|This chick is smoking hot
http://www.url2.com|This chick is also hot
Like I said I havnt tested the code, but I think that will work, it will just pull a random line from the text file, split the url & description on the | and spit it out.
Hope that helps.
