Take control of the preview image on platforms like FB, Twitter, Slack, messenger, ...

When I shared https://2019.indieweb.org/summit with a friend I noticed the link preview was @aaronpk's avatar. We should probably add an og:image meta tag with the IWC logo -- or at least include a high resolution version of the logo somewhere near the top of the page (before the RSVPs), which is more likely to be inferred as the image for link previews.

Renaming b/c the og:image in the name of this issue caused contention and we care more about the outcome than the methodology to get there.

The issue is: many services want to make an image preview for a given URL. They use very inconsistent algorithms for this. We have seen some undesirable things like using a single attendee or speaker's image as the "preview" image for the summit event.

Some options include:

• og:image is metacrap but very common.
• Requiring a large hero image might work for most.
• Maybe a combo.

We should start recording when this happens and where, so we can test.
