Dave in Michigan contacted me and wanted to know if it was possible to take the script used from this previous post and only display the last X number of pictures uploaded to a directory.

Something to note before you get started though. The script will read the entire directory so if you have a lot of images (more than 1,000) the page will load very slow. (if anyone has a good way to read a directory recursively based on filetime, please let me know)

Requirements:

1. PHP
2. jQuery (latest version)
3. InnerFade plugin (see docs for variables explanations and additional vars)

// Global Variables
$image_dir = "$_SERVER[DOCUMENT_ROOT]/imgs"; // directory on server
$image_relative_path = '/imgs'; // path to images relative to script
$file_types = array('jpg','jpeg','gif','png');
$image_time = '4000'; // seconds each image will display (4000 = 4 seconds)
$max_pictures = 6; // 0 = show all
$sort	= 'desc'; // desc = descending, or leave empty for no sort

if($handle = opendir($image_dir))
{
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
            $ext_bits = explode(".",$file); // finds file extensions
            foreach($ext_bits as $key => $value){
                if(in_array($value,$file_types)){
                    $filetime = filemtime($image_dir.'/'.$file);
                    $image_array[$filetime] = $file; // file creation time is the key
                }
            }
            
        }
    }
    closedir($handle);
}

if($sort == 'desc'){krsort($image_array);} // reverse sorts array by key

$count = 1;
foreach($image_array as $key => $value)
{
   $image_rotation .= '
';
   ++$count;
   if($count > $max_pictures){break;}
}

	< ?= $image_rotation; ?>
