Support Twitter image alt tags

jamietanna opened this issue 4 years ago · comments

As per https://blog.twitter.com/developer/en_us/a/2016/alt-text-support-for-twitter-cards-and-the-rest-api.html Twitter supports alt tags on their images. We should update Granary to return the alt tag for a Twitter image as well as the image itself, for better accessibility.

This doesn't seem to work in the HTML version. Tried it with https://twitter.com/edent/status/1343865082900602880 and got back

There is alt text on the original image.

Also broken are mf2-json, RSS.

It works on JSONfeed, as2, as1, as1-xml, atom,

Thanks for the report! One part of Twitter alt text handling was incomplete, so it wasn't making it all the way into mf2 JSON/HTML. That's fixed now, and I've confirmed that the alt text in your example tweet now shows up.

Thanks Ryan, that's sorted it now and I can see them 🙌🏼 thanks Terence for the assist, too
