WebViewer can display PDF images; why not in SuperContainer?

Before getting SuperContainer, a developer had set up a system for us where we uploaded documents via a website, copied the URL, pasted the URL in our FM database, and we could display the *image* of that document in a WebViewer. (WebViewer is pretty awesome with documents; if it's a PDF, you can zoom, rotate, etc.)

SuperContainer is a much easier upload process, but I'd like the option of displaying the document image in the database. Why does SuperContainer only display an image of the document name and file type?
