I use the shareware program paintshop pro available from  As
far as I know, unless you know the encrypting scheme for .bmp files,
mathematica is not capable of reading those files as arrays without
help from a third party program.

Paintshop pro can read in over 30 kinds of bitmap files and a few vector
formats as well.  Among its output formats are RAW, PGM(portable grey
map) and PPM(portable pixel map).
