I have the following code that pulls all the images from a folder and shows them on screen (reducing them via a thumbnailer etc). How can I get this to be pageable. EG show 5 images per page with a  page 1, page 2, page 3 etc linking to the next images?

Many thanks
Neil

<?php
 // loop through images folder and obtain all details of allowed files
 $imgFolder = 'thumbs/';
 $pics=directory($imgFolder,"jpg,JPG,JPEG,jpeg,png,PNG");

 // write details to screen
 if ($pics[0]!="") {
  foreach ($pics as $p) {
   echo '<tr><td class="photoarea">';
   echo '<a href="'.$imgFolder.$p.'" class="clickme"> <img class="photos" src="thumbnail.php?gd=2&amp;src='.$imgFolder.$p.'&amp;maxw=100 "/>';
   echo '<br><span>Enlarge</span></a>';
   echo '</td><td class="phototext">';

   $thisImg = $imgFolder.str_replace('.jpg','.txt',$p);
   if (file_exists($thisImg)) {
    $fh = fopen($thisImg, 'r');
    $theData = fread($fh, filesize($thisImg));
    fclose($fh);
    echo $theData;
   } else {
    echo $p;
   }


   echo '</td></tr>';
  }
 }

 function directory($dir,$filters) {
  $handle=opendir($dir);
  $files=array();
  if ($filters == "all"){while(($file = readdir($handle))!==false){$files[] = $file;}}
  if ($filters != "all") {
   $filters=explode(",",$filters);
   while (($file = readdir($handle))!==false) {
    for ($f=0;$f<sizeof($filters);$f++):
     $system=explode(".",$file);
     if ($system[1] == $filters[$f]){$files[] = $file;}
    endfor;
   }
  }
  closedir($handle);
  sort($files);  // sort by a-z
  return $files;
 }
