Went to Profile, clicked on Avatar section, then on Gravitar “More Information” and was taken to a page titled “Codex”. One of the paragraphs in about the middle of the page is titled: “Using Gravitars On Your Site”. It gives the option of opening a Gravitar account. I did that, and appeared to succeed in uploading a picture for said account. However, it didn’t show up here, so not sure what to do. Tried logging in and out.
