As you know, after 1.3.1 (if i remember good) in the game was set a filter to prevent to play online with the gostek pieces bigger than 16x16 pixels, and weapons 64x64 pixels.
This suggestion is for adding to the server.ini the option to allow to play on the server which allows it with image sizes bigger than the allowed ones, as this would be a possibility to try some great mods that we arent able to use after the limitations put by 1.3.1.
