Link to random img.

Jeg har det her stykke kode, som laver et random output i form af et billede. 


Jeg kalder filen med denne linie:
<img src='images/random/rotate.php' alt='Random Images'>


Kan jeg lave det så billede bliver et link til sig selv, som åbnes i et popup vindue for sig selv?


KODE:

$folder = '';

// Space seperated list of extensions, you probably won't have to change this.
$exts = 'jpg jpeg png bmp gif';

$files = array(); $i = -1; // Initialize some variables
if ('' == $folder) $folder = './';
$handle = opendir($folder);
$exts = explode(' ', $exts);
while (false !== ($file = readdir($handle))) {
    foreach($exts as $ext) { // for each extension check the extension
        if (preg_match('/\.'.$ext.'$/i', $file, $test)) { // faster than ereg, case insensitive
            $files[] = $file; // it's good
            ++$i;
            }
        }
    }
closedir($handle); // We're not using it anymore
mt_srand((double)microtime()*1000000); // seed for PHP < 4.2
$rand = mt_rand(0, $i); // $i was incremented as we went along

header('Location: '.$folder.$files[$rand]); // Voila!
?>
