Some of the avatars people are using make it difficult to read this site on a break while at work.  Is there a way to turn these off, or if not, would people be open to keep their avatars more G than PG-13 rated?

Personally, I'm not offended by any of them, but I see how someone could be by some.  Also some of them, while not offensive, could be considered unprofessional by a co-worker who comes up behind me at the office.

Thanks in advance for your consideration and response.  I'll figure it out either way.
