Can I remove (not change) my avatar; and how? (desktop)

Can I remove -- not change -- my avatar? If so, how?

When I try to edit my profile settings, I only see an option to choose a different avatar or to customize its appearance.

I don't see a "null" avatar or an option to remove the avatar. (Did I overlook it?)

But I thought I've seen some postings with no avatar. (Am I wrong?)

I am troubleshooting a problem with rendering thread webpages. It seems to be related to [styles.redditmedia.com](http://styles.redditmedia.com) . I think it gets stuck on rendering the avatar (?), since I don't see it during the "stuck" state.

(FYI, I work around it by continually reloading the webpage until it is no longer stuck and I see my avatar. But "continually" can be many times. And it is tedious.)

PS.... Tried changing my avatar to the simplest options, I think. Still a problem.
