Thought I would include what I wrote to get a random image from a directory.
<?php
$count = 0;
if ($handle = opendir('image_dir)) {
$retval = array();
while (false !== ($file = readdir($handle))) {
if (($file <> ".") && ($file <> "..")) {
$retval[$count] = $file;
$count = $count + 1;
}
}
closedir($handle);
}
shuffle($retval);
$current_image = $retval[0];
?>
