Question

I have this code set up for inserting any image that is uploaded to my “images” folder, right into a gallery I have…. My problem is that it kind of inserts them randomly.. I would like to set it up to insert the most recently uploaded picture to the end of the gallery “row”, any suggestions? Thanks

<?php

    $image_dir = 'uploads/images/';
    $per_column = 10;       

    if ($handle = opendir($image_dir)) {
        while (false !== ($file = readdir($handle))) 
        {
            if ($file != '.' && $file != '..') 
            {
                if(strstr($file,'.png'))
                {
                    $files[] = $file;
                }
                if(strstr($file,'.jpg'))
                {
                    $files[] = $file;
                }
                if(strstr($file,'.gif'))
                {
                    $files[] = $file;
                }
                if(strstr($file,'.jpeg'))
                {
                    $files[] = $file;
                }
            }
        }
        closedir($handle);
    }

    if(count($files))
    {
        foreach($files as $file)
        {
            $count++;
            echo '<li><img src="',$image_dir,$file,'" width="20" height="20" title="',$file,'"/></li>';
            if($count % $per_column == 0) { echo '<div class="clear"></div>'; }
        }
    }
    else
    {
        echo 'no pictures yet...';
    }

<?php

    $image_dir = 'uploads/images/';
    $per_column = 10;       

    $validExt = array(
        'png' => 'image/png',
        'jpeg' => 'image/jpeg',
        'jpg' => 'image/jpg',
        'gif' => 'image/gif',
    );

    if ($handle = opendir($image_dir)) {
        while (false !== ($file = readdir($handle))) 
        {
            $ext = strtolower(substr($file, -3));
            if (isset($validExt[$ext])) 
            {
                $stats = stat($image_dir.$file);
                $files[$stats['mtime']] = $file;
            }
        }
        closedir($handle);
    }

    $count = 0;
    krsort($files);

    $cnt = count($files);

    if($cnt)
    {
        foreach($files as $file)
        {
            $count++;
           echo '<li><img src="' . $image_dir . $file . '" width="20" height="20" title="' . substr($file, 0, -4) . '"/></li>'.chr(10);
            if($count % $per_column == 0) { echo '<div class="clear"></div>'; }
        }
    }
    else
    {
        echo 'no pictures yet...';
    }
