the struct for the aux_rgbimagerec is in glaux.h
basically it is
sizex
sizey
unsigned char *data
so all you have to do is save *data to a file. It makes it easier if you also save sizex and sizey so you know how big the image is.
the default size of the actual structure is sizex*sizey*3 as it is a 3 element array, red green blue.
fwrite(out,sizex*sizey*3,1,data) or something like that (forgot the order of fwrite) will do it for you, then jsut use malloc and fread to get them back in again.

ps - when you said it only saves four bytes, that is because you are saving the pointer, ie a long, not the data it self.
