How to move images not used in the document to outputs

[nandac]

Dear Folks,

I have a requirement where I need to move an image to the outputs directory so that it can be used as an open graph image/thumbnail.

At present, I find that only images attached to the blog content get moved to outputs. Therefore if the open graph image is not used in the blog content it will not be available on the website.

The open graph image is specified using a metadata attribute in the blog header like so:

title: "<title>"
author: "<author>"
opengraphimage: "something.jpg"

The directory structure for the blogs is:

├── content
│   ├── CV
│   │   └── cv.pdf
│   ├── blogs
│   │   ├── blog
│   │   │   ├── blog.md
│   │   │   ├── images
│   │   │   │   ├── open-graph-image.jpg

My open graph image will ideally live in the images directory under the blog-specific directory named blog in the above example.

I also do not have control over what the name of the open graph image will be.

I could get around the issue by placing all open graph images under the content/images directory where I place the favicon.ico for the website but I want to know if there is a better way.

I have tried using STATIC_PATHS and EXTRA_METADATA_PATHS but I am not sure if the answer lies there or if I am just using the wrong settings.

I hope someone can demystify this for me and put me on the right track.

Thanks in advance.
