As a start, I uploaded this photo to my profile:
Just wanted to mention that since I rarely take pictures of myself, it is always difficult to find a good picture of me.
This one is rather artsy, and may even be considered to represent the photographic procedure - note that I am reflected on a polished metal plate full of scratches while I am taking the picture. The definitive classic in reflexive autoportrait photography. I chose it not (only) because of that but because I cannot be seen. :-)
