@bcworkz Just writing back to say I implemented your idea of adding a column to the list table. Thanks!

It was fairly easy to do following this guide:
“How to Modify or Add Custom Columns to Post List in WordPress Admin”
https://awhitepixel.com/blog/modify-add-custom-columns-post-list-wordpress-admin/

And using the hooks ‘manage_media_columns’ and ‘manage_media_custom_column’

This is a good enough workaround for me now, but if any others have another possible solution for this let me know!

@bcworkz Adding a column to the list table isn’t a bad idea. I’ll have to look into how much of a lift that is. Before now, I haven’t done much in terms of adding features to the wp-admin pages (mostly removing them :P).

Good question about being sure the image isn’t used outside of a posts context. It is beyond the scope of my project right now. The WordPress instance I’m working with does not support a traditional website, it publishes data to REST API only so this is not a concern.
