Where do you get the skin for vehciles (The flat picture)

[Chripper!]

So where do we get the skins for vehciles to actualy mod a skin..?
And actualy, how do you apply your skin after?

[Geo]

You get the bitmap files from your game, and you don't apply them, just inject the modified image over the existing one!
