You might try converting the bitmap you have to a standard TIFF, using
some graphics program that supports those formats (i.e. read in the
file and save it as a TIFF).

Then I would checkout the ReadTIFF package by Simon Chandler on
Mathsource.  Be forewarned this package needs the fast binary files
package by Todd Gayley also on mathsource.  I have not been able to get
this latter package to work on my system ( PC running NT4.0 with math. ver
3.0).  However it does seem to install smoothly on a typical powermac.  

An alternative would to check out the electronic supplement to A.B.
Watson's article in The Mathematica Journal.  He has a ShowImage[]
command which will display imagedata stored as a matrix (list of lists)
of grayvalues.
