IconGuy: By making use of my Hacking Skillz, I have gathered that the picture located at http://stijn.fuzic.nl/hd/gabberfriend.jpg portrays Gabber's friend - someone supposedly related to Stijn (who has a subdomain at fuzic.nl, and therefore most likely is Dutch). "/hd" probably means that the folder somehow reflects his harddrive.

I hope I was of help!
