Armando Perdomo, a friend of mine, has created a new STS-122 picture group on flickr. so if you go view the launch or have interesting STS-122 pictures from some other source, you are invited to post them there. And, of course, everyone is invited to view the pictures. Typically, content comes in shortly after launch.
Armando did a similar effort for STS-120, I recommend viewing that picture pool to everyone.
