When I try to build the gallery using buildgallery.php, it do not create any thumbnails only a big white X. I have try to close and open my browser, but nothing happens. When I look at the server in the thumbnail folder, it is empty. Can some one help me here ?

( buildgallery.php version 1.9, running under php version 5.2.3, GD library version 2.0.34)
