why is my link card image not showing?
paste the url. we check everything we have ever seen break a card in production.
fetching as twitterbot…
the card, as x would render it
the nuclear option
if every check passes and x still shows no image: upload the cover to pbs.twimg.com (post it in any tweet, copy the image address), and point og:image / twitter:image at that url. x always renders its own cdn.
