GDLib til gallerier

Hvordan gør jeg bedst brug af gdlib til et galleri? Læste artiklen gdlib del 1 herinde, men synes det var det ene eksempel efter det andet, uden at vide hvilket jeg skal bruge.

Har 2 gallerier og rigtig mange billeder liggende, orker ikke at skulle fordoble dem med manuelle thumbs.

Nogen der kan hjælpe med det?

<?
$gallery = $_GET['gallery'];
$fullpath = "/customers/emilbp.dk/emilbp.dk/httpd.www/gallery/".$gallery;

# Constants
$image_base = $fullpath;
$max_width = 100;
$max_height = 100;

# Get image location 
$image_file = $_GET['img'];
$image_path = $image_base . "/$image_file";

# Load image
$img = null;
$ext = end(explode('.', $image_path));
if ($ext == 'jpg' || $ext == 'jpeg' || $ext == "JPG") {
    $img = @imagecreatefromjpeg($image_path);
} else if ($ext == 'png') {
    $img = @imagecreatefrompng($image_path);
# Only if your version of GD includes GIF support
} else if ($ext == 'gif') {
    $img = @imagecreatefrompng($image_path);
}

# If an image was successfully loaded, test the image for size
if ($img) {

    # Get image size and scale ratio
    $width = imagesx($img);
    $height = imagesy($img);
    $scale = min($max_width/$width, $max_height/$height);

    # If the image is larger than the max shrink it
    if ($scale < 1) {
        $new_width = floor($scale*$width);
        $new_height = floor($scale*$height);

        # Create a new temporary image
        $tmp_img = imagecreatetruecolor($new_width, $new_height);

        # Copy and resize old image into new image
        imagecopyresized($tmp_img, $img, 0, 0, 0, 0, 
                         $new_width, $new_height, $width, $height);
        imagedestroy($img);
        $img = $tmp_img;        
    }    
}

# Create error image if necessary
if (!$img) {
    $img = imagecreate($max_width, $max_height);
    imagecolorallocate($img,0,0,0);
    $c = imagecolorallocate($img,70,70,70);
    imageline($img,0,0,$max_width,$max_height,$c2);
    imageline($img,$max_width,0,0,$max_height,$c2);
}

# Display the image
$copyto = $gallery."/thumb/".$image_file;

imagejpeg($img, $copyto, 100);

if($_GET['createthumb'] == "yes") {
header("Content-type: image/jpeg");
imagejpeg($img);
}
header("Location: index.php?gallery=$gallery");


?>

Mon ikke du kan bruge det til noget.
