<?PHP
//initialize variables
$data_file = "images/list.txt"; //list of image names store in text file
$thumbnail_dir = "images/thumbnails/"; //thumbnail directory
$num_rows = 5; //images per coloum
$photos_per_row = 4; //images per row
$photos = file($data_file);
$total_photos = sizeof($photos);
$photos_per_page = $num_rows * $photos_per_row; //photos per page
//check to see if the start variable exists in the URL.
//If not, then the user is on the first page - set start to 0
if(!isSet($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 + $photos_per_page;
?>
<?PHP
for ($row=0; $row < $num_rows; $row++){
print("<tr>\n");
for ($col=0; $col < $photos_per_row; $col++){
if($i < $total_photos){
$thumbnail = $thumbnail_dir.trim($photos[$i]);
$thumb_image_size = getimagesize($thumbnail);
$image_size = getimagesize(trim("images/$photos[$i]"));
print("<td align=\"center\"><a href=\"photo_display.php?photo=".trim($photos[$i])."\" target=\"new\">
<img src=\"".$thumbnail.
"\" ".$thumb_image_size[3]." border=\"0\"></a></td>\n");

print("<td></td>\n");
}
$i++;

print("</tr>\n");

//end table
?>
</table>
<div align="center">
<?PHP
//print out navigation links
if (($start == 0) && ($next_start < $total_photos)) {
