I have my EFF 20 pick that cost me $100 USD and I did /mcpainter imagemap link.png and it overwrote my pick and now it's gone. /mcpainter imagemap even works on blank inventory slots without a map allowing for eco exploits selling maps...
/mcpainter imagemap also overwrites my friends maps with my new images...
