HTML: <img src="/path/to/dir/random.php" />
random.php:
<?php
$dh = opendir(dirname(__FILE__));
$images = array();
$img_extensions = array('jpeg','jpg','png','gif');
while (($file = readdir($dh))!==false){
if(is_file(dirname(__FILE__).'/'.$file)){
preg_match('/([^.]*)$/si',$file,$matches);
if(in_array(strtolower($matches[1]),$img_extensions)){
$images[] = $file;
}
}
}
closedir($dh);
$chosen ='./'.$images[rand(0,count($images)-1)];
$size = getimagesize($chosen);
header("Content-type: {$size['mime']}");
readfile($chosen);
?>
