It would be nice if you could make like .glist files or something similar, the format is like
PHP Code:
GLIST
block.png 0 0 32 32
funky_tile.png 0 0 16 16
and you can import these lists, and the gani editor adds them. This way, you could even make a script like what you guys were suggesting, select the image, and then hit export, saves either on the server, or in scriptfiles, then you import the list. Exporting could also be done with default gani editing.
But ofcourse, this will never get done.
