I used the only picture available at work, which is the one on this entry.
However, I obviously want to use a more TP related one.
I've found a good shot I took of him at the 2004 Con wearing the spider-web cloak. I've cropped others out of it but I'm not sure of the legal position with regard to putting it up on a website. I suppose as others put thier photos up it will be Ok, but there again they are putting them up on sites that have limited visibility, unlike Facebook.
