Hi acrylian!
I already have an image with the same name inside the album. When I choose another theme it works fine (also with thumbnail). I think the problem is that the image (thumb) is send to i.php wich checks if there's a image with the same name and then generates the thum b with the watermark. This one should be send to the refelct.php wich is used by ImageFlow. I have no skills in that detail. Maybe someone else can help :-)
Thanks that you like it. It's just a technical test. The final theme will look a bit more like iTunes with the possibillity to choose between ImageFlow and list view.
Thanks, lordcoffee
