Display Random Image with PHP
I use this script to display a random avatar for my profile on a chatroom. Stick your images in a subfolder called ‘avatars’ and reference this script as if it were an image and you’re away.
$extList = array('gif' => 'image/gif','jpg' => 'image/jpeg', 'jpeg' => 'image/jpeg', 'png' => 'image/png');
if($handle = opendir(getcwd() . '/avatars')) {
$pics = array();
while (false !== ($file = readdir($handle))) {
if($file != '.' && $file != '..') array_push($pics, $file);
}
closedir($handle);
$img = $pics[array_rand($pics)];
$imageInfo = pathinfo($img);
header ("'Content-type: ".$extList[$imageInfo['extension']]."'");
@readfile('avatars/' . $img);
}
