DaniWeb IT Discussion Community - php photo gallery extra code needed

Hi i have this code to create a photo gallery on my website.

<html>  <head>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

<meta name="GENERATOR" content="Microsoft FrontPage Express 2.0">

</head> <body bgcolor="#FFFFFF">

<div align="center"><center>

<?php

$a = '0';

$filepath = "thumb";

$url_path = "main";

$dir = dir($filepath);

echo "<table border=\"0\" cellpadding=\"5\" cellspacing=\"5\" width=\"75%\">";

while($entry=$dir->read()) {

    if($entry == "." || $entry == "..") {

        continue;

    }

    $fp = @fopen("$filepath/$entry","r");

if ($a == '0') {echo "<tr>";}

if ($a == '5') {echo "<tr>";}

if ($a == '10') {echo "<tr>";}

if ($a == '15') {echo "<tr>";}

?><td>

  <a href="<? echo "$url_path/$entry" ?>">

  <img src="<? echo "$filepath/$entry" ?>" alt="<? echo $entry ?>"></a>

  </td>

<?

$a = $a + 1;

}

?>

</tr>

</table>

</center></div>

</body>

</html>

i was wondernig what code would be needed to limit the gallery to only show 10 images per page and to add links at the bottom to allow progression through the gallery.

many thanks
