Wm:
Create your array in PHP:
(based on http://www.php.net/manual/en/function.readdir.php)
<script>
var fadeimages=new Array()
<?php
$thisdir = '/path/to/images';
$i = 0;
if ($handle = opendir($thisdir)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
echo "fadeimages[$i]=$thisdir$file\n";
}
$i++;
}
closedir($handle);
}
?>
