Thanks, great stuff.  This just came in action in a Slack channel.  It
showed up as attached.  IMO the image at 900x928 is a little bit on the
large side.  Slack resized it to about 1/4 of that for me, but still it
seems excessive.  Do we maybe have a smaller one we can use?

Another thing to note is that the og:article:author doesn't show up
anywhere.  I think this is just Slack's fault.  I don't know if that can
be fixed.  Any ideas?
