Lagre dette som avatar.php

<?php
$array_files = array();
if ($handle = opendir('avatar'))
{
        while (false !== ($file = readdir($handle)))
        {
                if ($file != "." && $file != "..")
                {
                        $array_files[] = 'avatar/'.$file;
                }
        }
        closedir($handle);
}
$count_files = count($array_files) - 1;

if ($count_files)
{
        $rand_file = rand(0,$count_files);

        $fileext = substr(strrchr($array_files[$rand_file], "."), 1);

        switch( strtolower($fileext) )
        {
           case 'png':
              header("Content-type: image/png");
              readfile($array_files[$rand_file]);
              break;

           case 'gif':
              header("Content-type: image/gif");
              readfile($array_files[$rand_file]);
              break;

           case 'jpg':
              header("Content-type: image/jpeg");
              readfile($array_files[$rand_file]);
              break;
        }
}
