You also can use another method and that is not to limit your self the
defined array, instead you can create the array by using glob, for the
existing files, and simpy using count to return the value of items in
your existing array.

<?php
$picture_array = glob("*.*");
$rand_no = rand(0,"count($picture_array)");
echo "<img src=\"".$picture_array[$rand_no]."\" />";
?>
