Opengraph help

This is better but still a little confusing. With leaf bundles, how do I access page resources within the frontmatter?

For instance, this does not work when I put featured.webp into a subfolder alongside the post
+++
header_img = “featured.webp”
+++

Instead I have to something like:
+++
header_img = “posts/this-post-name/featured.webp”>
+++
It seems error prone to have to reference the folder name to access an image.

But referencing an image later after the +++ does work. i.e.

+++
frontmatter
