You would have to add something like this to and have it included into your header:

PHP Code:

<?php
function getRandomFromArray($ar) {
    mt_srand( (double)microtime() * 1000000 );
    $num = array_rand($ar);
    return $ar[$num];
}

function getImagesFromDir($path) {
    $images = array();
    if ( $img_dir = @opendir($path) ) {
        while ( false !== ($img_file = readdir($img_dir)) ) {
            // checks for gif, jpg, png
            if ( preg_match("/(\.gif|\.jpg|\.png)$/", $img_file) ) {
                $images[] = $img_file;
            }
        }
        closedir($img_dir);
    }
    return $images;
}

$root = '';
// If images not in sub directory of current directory specify root 
//$root = $_SERVER['DOCUMENT_ROOT'];

$path = 'forum/images/stylename/newlogos';

// Obtain list of images from directory 
$imgList = getImagesFromDir($root . $path);

$img = getRandomFromArray($imgList);

?>

Then wherever your header image is place this:

PHP Code:

<img src="<?php echo $path . $img ?>" alt="" />

Or at least assign the above snippet code as a Vb template code and display this in your style.

I think I explained it correctly, if anyone else can elaborate please do as my thoughts sometime scatter

Hope this helps. Let me know if it does!
