Support for og:image:alt

Sad to see this plugin is stuck on no update land. Someone please buy it! It works most flexibly for my sites (I could care less about facebook) as it lets me fine tune Twitter card data like no other, plus it’s not part of some SEO bloatware.

Anyhow, I see there there is no support for the accessibility feature in the og protocol for og:image:alt (or the comparable twitter:image:alt.

I was able to convince the JetPack developers to make their og features use this metadata which adds alt descriptions for image. I wish I could make that happen with this one.
