A IM will read in the image before identifying it and it does not use
24 bit values, IM probably will not be able to tell you.
You will need a specific BMP identification program, such as provided
for other formats. EG: jpegtrans pngtrans giftrans
I don't know what you can use, but maybe the UNIX file comannds
can tell you.
