When a user uploads a large photo, a horizontal scrollbar is displayed.
It would be better if the photo was being automatically resized to (for example) 800 x 600 and you could click on it to display the large version.
Phorum does this and the larger photos have a maginifier icon on the top left corner.
PS. It would be great if we knew what web wiz thinks about our suggestions. If they are being considered or if they are rejected.
