Twitter Image and Title

[scottwater]

I noticed Twitter is no longer pulling the image from og:image.

This change adds the twitter:image meta tag if an image exists on the post.

It also adds the twitter:title meta tag as well.

Just tested https://jekyllrb.com/news/2018/11/04/jekyll-3-8-5-released/ on https://cards-dev.twitter.com/validator, and it does show the og:image.

@DirtyF Yes, I can see that image is working. My guess is there is something going on with caching or priority in the image look up. I had an example ready to send you which showed the how my fix worked, but when I double checked Twitter did pick up the og:image but it was missing the first time.

I will see if I can create a more definitive demo.

Having said that, either way, it still feels like a good idea to set the twitter:image and twitter:title.

Thanks,
Scott

I have not been able to duplicate this issue again, but I still believe these changes are helpful long term.

OpenGraph is listed as a fallback on twitter's site so I'm happy to see us provide first class support for this. Especially since they keep breaking it. 😐
