One of these days, I will add a whole new set of images to the randomizer at the top. I don't know about you, but I'm getting quite bored of the ones in rotation at the moment [except that amazing picture of a real-life UFO - I've actually had NASA on to me about that picture, they want me to remove it immediately for some reason]. It was taken by Dan, so why don't you email him and ask him about his close encounter.
So yes, more images are definitely needed and don't forget that - if you like - you can send a 400×170 jpeg, and I'll include it there. The current theme - which happened entirely subconciously and I don't know why - is ‘flight’.
