So, it's relatively straightforward to add a background image to a region through the theme with custom css.
I'm trying to find a way to do this through the User Interface, either through a contrib module or some other trick.
We have the option to add a background image to a hero block. How about adding a background image to a region?
I'm open to any of the following types of answers:
1) A Drupal module that might be ported to accomplish this
2) Some pseudo code on how to write a module for this feature
3) Some creative use of core features that might make this possible.
CSS injector doesn't count! (It's a reasonable option, but I thought of that already).
