Thanks, it has been changed back.
How high would you prefer the maximum filesize?
The current hosting only allows 500MB of disk space usage; 12% of which is currently filled by the photoboard. If we want to host larger images, that space would fill up even quicker.
I made the photoboard with the intent of it being a place where the photos would be stored forever, but it could just as easily have a system where every new image pushes off the oldest from the board.
