Here is a simplification of HeadRoom's image shuffle code
<?php
$image_dir = 'images/';
if ($handle = opendir($image_dir)) {
$retval = array();
for ($count=0; $file = readdir($handle); $count++){
if (($file != ".") && ($file != "..")) {
$retval[$count] = $file;
}
}
closedir($handle);
}
shuffle($retval);
$current_image = $retval[0];
?>
