So, I have been using the new Media Entity module, along with some of the other media modules on some websites, and generally I like it. I find it awesome to be able to create different Entity Browsers, based on tagging, so if I'm adding hero images to my Hero Image block, my entity browser can have a special view.
In order to use the Hero image from my block as a background image, I had to Google a little. Hence my post, I wanted to document what I did, if for nothing else, my own reference. So here we go.
