switch ( $_GET['cmd'] ) {
    case 'link':
        if ( $_SESSION['url'] === '' ) {
            header( 'Location: http://google.co.uk' );
        }
        else {
            header( 'Location: http://' . $_SESSION['url'] . '/' );
        }
        break;
    default:

        // Add images to the array below, you can have as many as you want. Btw its ur job 2 do the size enit fosho
        
        $images = array(
            array(
            'image.png' , 'url2site.com'
        ) , array(
            'test.gif' , 'url2site2.com'
        )
        );
        
        // Choose image to display!
        $image = $images[array_rand( $images )];
        $image_source = $image[0]; // url 2 img
        $image_url = $image[1]; // url 2 link
        
        $file = @file_get_contents($image_source); // Read the file, get the contents.
        $img = imagecreatefromstring($file);      // Create the image from the string
        
        header("Content-type: image/png");  // Lets use PNG, it's better.
        imagepng($img);  
        imagedestroy($img);
        
        $_SESSION['url'] = $image_url; // Set the link session.
}

In their TOS, it says they don't allow a banner exchange (I basically revised it after some-what-****-of-a-josh put **** on his acc) I also think the "random" is not that random, seems always to hit number #1

(That's not me btw {Luckily ahah.})
