When I try to change my avatar by clicking "Change Picture" under my profile, I am taken to www.gravatar.com. But I have an myOpenId account with an option to change my profile picture. Which one actually changes my avatar?

Side Note: When I tried changing my avatar in my myOpenId preferences, nothing changes on my Stack Exchange accounts. When I tried gravatar.com, nothing happens except when I click "accounts" tab under my profile, under the "related accounts" all the avatars have changed to the one I wanted but have not changed on the actually sites.

Side Note 2: No matter what I try, my avatar is stuck on that e-mail hash code image creator. Could it be a conflict between myOpenId and Gravatar.com?
