Thanks, Frances.

Yes, you can. The photo is part of Admin, Settings - a separate button. /g/GroupManagersForum/wiki/Quick-Start-for-Group-Formation#Cover-Photo-button3A

I've set all these, but the home page HTML still has:

<meta property="og:url"           content="/g/zoom-rxx" />
<meta property="og:type"          content="website" />
<meta property="og:title"         content="zoom-rxx groups.io Group" />
<meta property="og:description"   content="Discussion group for users ..." />
<meta property="og:image"         content="/img/logofull.png" />

As you can see, the og:image refers to the generic groups.io logo, not my group image.
