I've seen this php code to get randomized images from a folder. The idea is really good, but we can do it better. I don't like the solution, to send headers with the randomized image, but first step, a little code cleanUp.

Works with php 5.3+

PHP Code:

<?php

$images = array();

try {
    foreach (new FilesystemIterator(dirname('images/YOURFOLDER/*')) as $file) {
        
        if (!preg_match('#^(.*)\.(gif|png|jpg)$#i', $file)) {
            continue;
        }
        
        $images[] = $file->getPathname();
    }
}
catch (Exception $e) {
    // do something like -> header('Location: images/background/alternativeImage.jpg'); 
}

$image = mt_rand(0, count($images) - 1); 
header('Location: ' . $images[$image]);

Don't use

PHP Code:

?> 


to close the php code! We don't need it...

Cheers
