I suggest looking at the PPM format (portable pixel map)  It is a very
simple format, and I have used it for maps I've made.  In a nutshell,
you output the color values one after another for each pixel.  There is
a binary and even an ascii text mode.  The header is a very simple.

You can view and edit these PPM files in various unix paint programs
(gimp, etc).  Paint shop pro, and I think photoshop, for windows also
supports it.

Sorry, I don't have any references handy.  Search the net for references to
netpbm and ppm.
