The script is for my vbulletin forum in PHP which we can stick our affiliate banners with their links so that they rotate on refresh.
The code is as follows:
$total = "6"; //6 - change to how many images you have
$file_type = ".jpg"; //change to file type
$image_folder = "random"; //location of folder
$start = "1"; //which image you want to load first
$random = mt_rand($start, $total);
$image_name = $random . $file_type;
echo "";
