There is still the problem to link the image in your source code. It's 
an easy task if it's an XPM (you can include it with #include), but not 
that easy if you want to use a binary format. There is a portable way to 
do this without external programs that convert images in source files?

I've been able to use this trick to include a binary file in my source 
with objdump, but it's not portable at all :) (but it was for a firmware 
so it was ok :) )

[from Makefile]

firmware.o:
    objcopy -I binary -O elf32-i386 -B i386 --rename-section 
.data=.rodata,alloc,load,readonly,data,contents firmware.bin firmware.o

[from the source code using it]
extern char     _binary_firmware_bin_start;
extern char     _binary_firmware_bin_end;

#define firmware_ptr      &_binary_firmware_bin_start
#define firmware_end_byte &_binary_firmware_bin_end
#define firmware_length ((unsigned long)(firmware_end_byte) - (unsigned 
long)(firmware_ptr))
