Image chosen for onebox / opengraph on category page is unexpected

The blackness:

– has anyone encountered that blackness before?

An issue with Twitter, I assume.

If it helps to understand possible causes of the misreprentation above, here’s a screenshot of an earlier view of the same tweet (probably taken soon after it was posted):

In that early shot, Twitter’s representation was of the first of the three links. There’s the /about text for the forum.

In all later views of the same tweet, in a variety of browsers (including non-extended Firefox 53.0), Twitter’s representation is of the third of the links.

You are referring to oneboxing, which is the opengraph or oembed tags for a page. View source to see what image was selected in those tags, on the target page.

Use Iframely URL Debugger - Open Graph, Twitter Cards, oEmbed to troubleshoot.

Generally if you don’t like the image being chosen for oneboxing, remove it from the page by pressing the edit button.
