Dr Dobbs have a couple of articles on the BMP format; one includes source
code to read a .bmp file into an array.  Look at 94/09 and 95/03, IIRC
the article was titled "When is a Standard Not a Standard", refering to
Microsoft's practice of changing the format with each version of Windows.

Use malloc() to dynamically allocate the memory at run-time.
