You'll need to edit the map so that the Warthog gun riticule is nothing.
How to do this:
1. Open eschaton and go to dependency swapper.
2. Open the Weap tag and go to Warthog Gun.
3. Change wphi from Warthog Gun to Master.
After doing this open up the hacks then open up the Halo Demo. Start the Third Person Hack then get in the Warthog Gun then get out Immediatly after. You should be in third person. This usually takes many tries.
After doing this get into the spot you want your screen shot in. Start the Clone Hack. The reason I had you take the riticule off is that for some reason the Warthog Gun riticule happens when you clone. For a good screenshot you want this gone. Being in third person you should be able to move around your character after cloning. Get in a place you like and take the shot.

Even works in campaign!
