Hey that is very cool. I will work on the server side to make it handle those uploads then.

i will have a look at the tileset files and the code next week.

the code has hardcoded assumptions of 1365 tiles per tileset all over the place. Given that a file will take 4-8kb of a file system anyway, I don't see enormous disk space savings. But in the long run, I am fine with the change. We would need to have both types of tileset files in parallel for quite a while and modify mod_tah.c to cope with it and modify the server to cope with it.
