If you do end up writing your own program, consider converting it to the
PGM format.  Just about the dead-simplest format around.

http://netpbm.sourceforge.net/doc/pgm.html

While this isn't a "binary" format, it is extremely easy to write code
for and there are lots of free graphics viewers that can handle it.
InfranView and the GIMP should handle it.

P2
# my file.pgm
1024 768 
255
1 2 3 4 ... 


768 ... 

P2 = Portable Grayscale Map
# = comment line, file name is common here
X Y = size
B = bit depth

Where you have stripped out each byte from the binary stream and written
them out as a 1024 x 768 matrix.
