Sorting results of a PHP Thumbnail Script

I found the following PHP script on the net which is taking a directory of images and creating thumbnails. This part works great, expect I've noticed the sorting is off. Best I can tell is it's using file names, I'd like to use creation date as I'm sorting a directory of images created from a security camera.

Any input and a bit (ok, a lot) of direction would be great as I don't have a lot of PHP experience, but can get around somewhat.

Thanks again for the help!

I have added a very dirty way of sorting (not efficient). Change below line to SORT_DESC or SORT_ASC in the code to sort descending or ascending.

arraySortByColumn($exifData, 'time', SORT_DESC);

Your script with added sorting functionality:

<html><head><title>Snapshots</title></head>
<body bgcolor='white'>

<?php
$folder = '.';
$dir = getcwd();
DirStat($folder, 0);
chdir($dir);
$FolderSize = ByteSize($FolderSize);
$FileCount=$FileCount-2;
?>

<h2 align=center><?php echo date('m/d/Y H:i:s') ." - $FileCount Snapshots - $FolderSize";?></h4>

<?php

$imagens='';
$exifData = array();
$dn = opendir('.');
while (false !== ($file = readdir($dn))) {
 if ($file == '.' || $file =='..' || $file =='index.php' || $file =='Thumbs.db'){
        //print "<a href=$file>$file</a><br>";
 }else{
        if (is_dir($file)){
                print "<img src='/imagens/diretorio.png'>&nbsp;<a href='$file?dir=dirname(__FILE__)'>$file</a><br>";
        }else{
                $tamanho = filesize($file);
                $datetime = @exif_read_data($file);
                $m = 'bytes'; //
                if ($tamanho>1024) {
                        $tamanho=round($tamanho/1024,2);
                        $m = 'KB';
                } elseif($tamanho > 1024*1024){
                        $tamanho = round(($tamanho/1024)/1024,2);
                        $m = 'MB';
                }
                $exifData[] = array('time' => $datetime['FileDateTime'], 'file' => $file, 'tamanho' => $tamanho,  'm' => $m );

        }
 }
}

closedir($dn);
//change to SORT_DESC or SORT_ASC
arraySortByColumn($exifData, 'time', SORT_DESC);

     $imagens .= OutputThumbnail($value['file'], $value['tamanho'], $value['m']);

        $sort_col = array();
        foreach ($arr as $key => $row) {
            $sort_col[$key] = $row[$col];
        }
        array_multisort($sort_col, $dir, $arr);
    }

function OutputThumbnail($image_file, $tamanho, $m)
{
        if (file_exists($image_file))
        {
                $size = GetImageSize($image_file);
