First, I'm a php newbie. I got some books on order so I can learn PHP but in the mean time I'm stuck on this and need help!
I got this script from the webmonkey website. The problem is it only works with register_globals turned on and I was hoping some one could rewrite it so it can run with register_globals turned off.
<html>
<head>
<title>photo gallery</title>
<script language="javascript">
<!--
function photo_open(link, width, height)
{
var photoWindow = window.open(link,"photo",'toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=0,resizable=0,width='+width+',height='+height);
}
//-->
</script>
<body bgcolor="#FFFFFF" text="#000000"link="#00CCFF" alink="#00CCFF" vlink="#00CCFF">
<table cellpadding="2" align="center" cellspacing="2" width="80%" border="0" align="center">
<?PHP
//initialize variables
$data_file = "list.photos";
$thumbnail_dir = "thumbs/";
$num_rows = 5;
$photos_per_row = 4;
$photos = file($data_file);
$total_photos = sizeof($photos);
$photos_per_page = $num_rows * $photos_per_row;
//check to see if the start variable exists in the URL.
//If not, then the user is on the first page - set start to 0
if (!isset($start)) {
$start = 0;

//init i to where it needs to start in the photos array
$i = $start;
$prev_start = $start - $photos_per_page;
$next_start = $start + $photos_per_page;
for ($row=0; $row < $num_rows; $row++){
print("<tr>\n");
for ($col=0; $col < $photos_per_row; $col++){
if($i < $total_photos){

$thumb_image_size = getimagesize($thumbnail);
