I have code that does this for Photoshop "raw" format.  I don't recall whether 
it includes the byte-swapping that is required for PC's (the code runs on a 
big-endian Mac).  If your picture depth is one byte per pixel, it doesn't 
matter.

Let me know by direct e-mail if you are interested.  I would also be curious 
to talk to you about your application, since I have done work in image 
processing.
