I apologize profusely in advance if this is either a stupid question or the wrong place for it. I have noticed a number of people with a picture or avatar below their name on their forum posts but I can't seem to find a way to add one myself. Is it a simple option that I'm simply overlooking somewhere? Is there a prerequisite (a minimum number of posts, for example) which I have not yet met? Some other reasonable explanation? I'm mainly just curious but appreciate any helpful information.
