I think this is exactly what I'm looking for, but it's not setup *quite* as I want. Maybe it could be?
What I want to do is basically this:
Have a CF that contains an image, for a page.
Be able to (ideally with shortcodes) include that CF on many different pages and posts. The image would also contain a link to that page. I don't want to make the URL embedded in the CF.
I don't mind doing some hacking up of things, I'm just not quite sure what to do. So far this plugin is the closest I can find to what I'm looking for...
