By "bmp," I am assuming that you are wanting to generate Windows
Device Independent Bitmaps.

If you are using Mathematica 3.0 or later under Microsoft Windows,
you can simply select a graphic (the contents within the cell, not
the bracket of the cell containing the graphic) and perform the 
following menu command sequence.

	Edit -> Save Selection As -> Bitmap (BMP)

If you are running under Unix, and you have the PBMPlus or netPBM 
toolkits installed, you can do something like this.

Display["!ppmtobmp > graphic_file.bmp", g3, "PBM"]

Mathematica 4 users can use:

Export["graphic_file.bmp", g3, "BMP"]

regardless of platform.
