I never did post a picture of my bag. It is the sort that has a space for a laptop as well as the space for the camera goodies.
It normally has the camera with my 17-40 attached to it and then the 50mm which is what is on my camera right now (it is the only lens that the close-up attachment fits) is in the bag too. The diffuser obviously takes up a heck of a lot of room...and not much less when it is broken down. I'll probably end up stashing it somewhere else eventually...stick it in its own bag and hang it off the outside or something, I don't know.
BTW...think I was gone due to computer failure when the baby showed, how did it go?
