Hi
Just google "chipguide", go to submissions. You will see you don't have to put in a name or emailadress.
Put in the image, a small text saying which CG number picture it is and don't forget to say you are the owner.
That is the easiest way, some admin will see it and in good time your picture will be on the chipguide.
Your email is only used to say "thank you" in a small message back.
Hope this helps.

Jo from Belgium.
