Haha, same. I had a lot of concerns about that actually, but I showed several of them (most, actually) to him live during the actual podcasts where I took the screenshots, and he thought they were funny. He even used on as the image for an update on the site about the podcasts. :xd:
I take screenshots of him straight from the live feed from his podcasts and then I edit them in Paint Shop Pro or GIMP (prefer PSP). That's all really. Or were you referring to something I did in specific pictures?
