Use BMP2GMP.exe to convert a bitmap file to a grayscale image that can
be viewed on the onHand.

At the DOS command line on your computer type:
BMP2GMP bitmapfile.bmp targetfile.gmp

Copy the targetfile.gmp to the onHand and use the GMPviewer to view.

Use the Filer editor to associate the .gmp files with the GMPviewer
program.
