So anyone can help me?

Here is a link that will get you started :

sort files by date in PHP

Getting the first or last file is merely getting the correct element from your sorted array :

$latest_file = $files[1];
$oldest_file = $files[count($files)];

You can create a image tag

echo '<img src="/dir/where/files/are/'.$latest_file . '" />';

For the rest, you can create links

for ($i  = 2;  $i <= count($files); $i++) {
   echo '<a href="/dir/where/files/are/'.$latest_file . '" />' . $latest_file . '</a>';
}
