If you mail a gallery posting to someone he recive a email wich contains links to the images in the gallery and you can click the link to display the image. But the links are malformed and cannot be open. I get a message from UBB.threads like his:
the graphic "http://www.dragonclan-forum.de/board/ubbthreads.php/ubb/download/Number/2545/filename/untitled1.JPG" cannot display, because he contains erros.
This message is in graphic (not text) and comes from the ubb.threads lightbox, I guess.
The real URL to the image is:http://www.dragonclan-forum.de/board/gallery/190/full/2545.jpg
But this isn't be parsed by the lightbox and display it directly (deep link).
