Hi Tom,
I was struggling to get a nice result with the header image until I added css to center the background image. It would be nice to have background image position feature in the header settings (I don’t see it there :?_
What about having the correct WP responsive image load for the screen and have the option of none at all. It seems that on mobile the benefit of no image is speed and a cleaner look in most cases.
What are your thoughts on this? (apart from show me the ongoing development cash)
