feature request: show first image on page as thumbnail/preview

[holtzermann17]

It seems this is a matter of writing a 'partial' but I'm not immediately sure just what it would look like. Here, someone is writing about how they do it in Hugo: https://discourse.gohugo.io/t/display-first-image-in-post-in-link-preview/10541/2

Sample page with an image on it:

https://exp2exp.github.io/writers_workshop

Reposted in Discord, no preview shows up (that's expected at the moment, but the feature request would be to generate a preview):

Yep, this could be done with a partial. I think this is a bit adjacent to Firn so I wouldn't add it to the docs, but for the most part, I think the process would look like this:

• add required [metadata]https://ogp.me/#metadata) to your head partial (if you have one)
• pass file metadata (from keywords, or just from title etc, into your head partial as a map (ogp-data).
• If you want images, you could probably store an image as a #+frontmatter key too!

Let me know if this works.
