I think that Stefan should just designate two files for uploading large files, one for the tileset and the other for the map, because those are really the only things that will be bigger than 64k that you'll be needing to upload on your playerworld frequently. So if he designates the file names playerworld_tileset.png and playerworld_map.png, these will be the only files that would be allowed to be uploaded that are over 64k.

Also this is good because if someone tries to change the name of a .exe file to playerworld_map.png, it would be noticeable that there is an error if players try to use their maps.
