Script To Select A Random Image

[CeleronXT]

On my forum, I'd like to make a sig.php for myself and have it randomly select an image to display. What code would be used to do this? I've seen it done before on another vB which is why I wanted to do this as well, but I'm not sure of the coding to use.

This should work:
srand ((float) microtime() * 10000000);
$images = array('./image1.gif', './image2.gif', './image3.gif');
$rand_image = array_rand($images);

header('Content-type: image/gif');
readfile($images["$rand_image"]);
