If you only have a few images to rotate, you could just set the content of $logos manually. Would result in a bit less processing time.

Something like:

PHP Code:

$logodir = "images/";
$logos = array
(
   $logodir . "filename.png",
   $logodir . "filename2.png"
);

function make_seed() {
    list($usec, $sec) = explode(' ', microtime());
    return (float) $sec + ((float) $usec * 100000);
}
srand(make_seed());

$logo = rand(0, count ($logos) - 1);
$titleimage = $logos[$logo]; 


Would save the server from having to list the directory every time a page was loaded.
