Hey, this is AeRoFeAr and i'm going to show you how to erase images in Halo 3.
First of all find some kind of print:
Next Put a teleporter or a spawnpoint on it:
Save your changes and end the Game
Then when you go to the thing you tried to erase your teleporter or spawnpoint will be there... delete it and the picture will erase
When you start a new game it will not be erased unless you leave the teleporter or spawnpoint there... Well that's all
Here's a map if you want to see them____---___
