Changing Background Image
If your talking about the loading screen then go to your halo folder and open 00000000.016 in paint. Edit that.
If your talking about the actual in game screen "the ui" then you can edit that with bitmaps using HMT i belive, but dont expect any like new links on the ui just like anew skin above the existion links.
