Even if the picture doesn't upload, it is still on your toribashian in-game. I learned this quite quickly by trying to re-equip my full texture set (new) and going in-game to play a few single player skateboard mods, and I said wow, there are my new textures. Just equip them like you normally would and go to single player OR multi player, doesn't matter, and see if it works, from there if it doesn't work, I don't know.
