Application Session array and diplaying images on other file

Good day to you all,
Session are always fun, this time I pushing 2 array to a session, one a list of folder and the other a list of files :

PHP Code:
<?php

session_start
(); 

?>




function ahah(url, target) {
  document.getElementById(target).innerHTML = ' Retreiving and loading image... <br/> Recherche et chargement de l\'image...';
  if (window.XMLHttpRequest) {
    req = new XMLHttpRequest();
  } else if (window.ActiveXObject) {
    req = new ActiveXObject("Microsoft.XMLHTTP");
  }
  if (req != undefined) {
    req.onreadystatechange = function() {ahahDone(url, target);};
    req.open("GET", url, true);
    req.send("");
  }
}  

function ahahDone(url, target) {
  if (req.readyState == 4) { // only if req is "loaded"
    if (req.status == 200) { // only if "OK"
      document.getElementById(target).innerHTML = req.responseText;
    } else {
      document.getElementById(target).innerHTML=" AHAH Error:\n"+ req.status + "\n" +req.statusText;
    }
  }
}

function load(name, div) {
    ahah(name,div);
    return false;
}



//  End -->
</script>



</head>

<body bgcolor="#ffffff" align="center" link="white" vlink="#cccccc" text="white">




<table valign="top">
<tr><td width="150px" valign="top">


<div
style="position:relative; 
 width:300px;
 height:480px;
 padding:0px;
padding-left:0px; 
padding-top:0px; 
 border-size:1px;
border-color:#000000; 
 overflow:auto;">

<?php
 
$directory 
"Art/";
function 
dirList ($directory)
{
 
    
//create 2 arrays - one for folders and one for files
   
$folders = array();
   
$files = array();
 
    
// create a handler for the directory
    
$handler opendir($directory);
 
    
// keep going until all files in directory have been read
while (false !== ($file readdir($handler))) {  
 
        
// if $file isn't this directory or its parent,
        // add it to the results array
        
if ($file != '.' && $file != '..')
       
        
// If file is directory, mark it in bold.
       
if(is_dir($directory.$file)) {
        
array_push($folders,$file);
        
            if (
time() - filemtime($directory.$file) < 604800) {
    
$folder_modified[] = "<span style=\"color:#DB1212;\"><img src=\"minus_icon.gif\" id=\"plusminusimg".preg_replace('/\//','_',$directory."".$file)."\" onclick=\"Toggle('".preg_replace('/\//','_',$directory."".$file)."'); return false;\" /><a href=\"#\" onclick=\"load('folder_view.php?dir=".$directory."&file=".$file."','boxdisp');return false;\"><b>".$file."</b></a>";

// Else not styled
        
}else{
        
array_push($files,$file);
     
$filenamecor substr($file0, -4);
    if (
time() - filemtime($directory.$file) < 604800) {
    
$file_modified[] = '<span style="color:#DB1212;">'.$filenamecor.'<span>';
} elseif (
time() - filemtime($directory.$file) < 31556926) {
    
$file_modified[] = '<span style="color:#003366;">'.$filenamecor.'<span>';
} else {
$file_modified[] = '<span style="color:#000000;">'.$filenamecor.'<span>';}
 
 
    }
    }
 
    echo 
"<ul id=\"".preg_replace('/\//','_',substr($directory,0,strlen($directory)-1))."\">\n"//start a new unordered list for every iteration through dirList
 
$dircor $directory;
    
// tidy up: close the handler
    
closedir($handler);
    foreach(
$folders as $folder=>$file) {
        
      echo 
"<li id=\"pic\"><div class=\"folder\">".$folder_modified[$folder]."</div>"//echo the folder name enclosed in a list item
        
dirList($directory.$file.'/'); //loop through the contents of $folder
      
echo "</li>\n"//close this list item after all files and folders in $folder have been looped through
   
   
    
}
 
    foreach(
$files as $key=>$file) {

      echo 
"<li id=\"pic\"><a href=\"index.html\" onclick=\"load('image_view.php?dir=".$dircor."&file=".$file."','boxdisp');return false;\">&nbsp;".$file_modified[$key]."</a></li>\n"//echo the file name enclosed in a list item
    
}
 
 
    echo 
"</ul>\n"//close the unordered list
}
       
$_SESSION['folders']=$folders;  
       
$_SESSION['files']=$files;  

dirList($directory);
When you click on a folder it bring
you to a page like that :


PHP Code:



<?PHP
session_start
(); 
$file $_GET['file'];
$dir $_GET['dir'];

?>



<html>
<head>

    <SCRIPT language="JavaScript">
    <!--
    if (document.images)
    {
      preload_image = new Image(25,25); 
      preload_image.src="http://test.peuplies.info/PHP/Photos_gallery/<?PHP echo $dir."".$file?>"; 
    }
    //-->
    </SCRIPT>
  


</head>
<body>


<?PHP

$dir 
$_GET['dir'];
$file $_GET['file'];
echo 
"<center><img src=\"".$dir."".$file."\" width=\"400px\"/></center>"


?>





</body>
</html>
How can I list the image in that folder reading from the session array the folder passed thru the url ?

Thanks !
