lol, all this trouble, while it was just converting to octal. of course, now that I know it, it makes sense.
For those that want to convert their image to a const unsigned char, like gimp does it. Here is my python code (it uses PIL).

- free as beer code snippet
- this code snippet creates from images in the "images" folder one images.c file
- the created file can be loaded in your C(++) program.
- so colors go from decimal to octal format
