Well after a hour or two of mapping out some things. I figured I would throw this simple little program together. It will connect to your Xbox Hard Drive using your Connectivity Kit (example: XSATA or XPort 360) and dump all the Halo 3 Screenshots you have. You just run the application, goto File then Dump Screenshots. This will save you some time instead of uploading to bungie.net.
Hope this makes life alittle easier on all you.
I would also like to thank Roofus for his awesome FATx Library that I used
Sorry for the rapidshare mirrors would be nice.
