Display Content PDF as an Image on a page

I am having difficultly figuring out how to use merge syntax and Content ID to display a PDF from our Content Library in an Image component. We store 1 Content record ID per related record which is all referenced within our models, but I can’t work out why I can’t see anything on our page

Have you seen this page?

Ainslie,

How do you store the Content record ID? Are you looking at the ContentDocument object or did you add a custom field or is it some other way? Is there a field that is a reference to an image or a File? Could you post a screenshot of your setup on the backend?

Thanks!
