yes yes... I suggested that obvious solution as early as the code was made... it's just a matter of getting around to doing it, taking into account the tileset would need to be readjusted when reuploaded, what if a pack includes a tileset already "generated" (could use a combination filesize name and/or hash in the J2T file) etc.. (plus does J2O's host have GD enabled?)

We're in the same boat. Nothing to be sorry about.
