To answer your question:\r\n\r\n> Is it possible that only feconf.SYSTEM_USER_IDS commits to an exploration? If yes, what we should display as an icon ? (probably, nothing? )\r\n\r\nGood question -- this can happen when a demo exploration is loaded. (In fact, I just tried doing this, and when I got back to the gallery, I got a bunch of errors because the URL\r\n```\r\nhttp://localhost:8181/preferenceshandler/profile_picture_by_username/undefined\r\n```\r\ngave a 404 error.)\r\n\r\nAnyway, I think these cases are rare, and it probably makes sense to just not display a circle at all in that case.\r\n\r\nI'll look at the commit in a bit more detail now!"}}
