I haven't put up a picture just yet. However, I would want my picture to be appropriate in a way that I just see my face. I don't want distractions from the clothing I am wearing or where I took the picture at. I just want others to see my face and that's about it.
I use the album cover from "In the Court of the Crimson King" by King Crimson. They were a very creative and inventive musical group.
