Or if you are looking at older posts, the picture may no longer be there.
O that was sort of what I was thinking. If I can ask a really dumb question where do they go?
Since the pictures are placed on other hosts (than beemaster.com) the pictures will only show up here unless the host of the pictures are not removing them. If people use pictures hosting services, and for some reason the picture hosting service removes their account, their pictures supposed to be shown here will be gone too.
