Page Header Background Image

Hi Tom,

I'm a little confused about the Page Header feature. I'm trying to make a subpage layout where there's a horizontal image at the top that goes full width. However, I'm confused that I have to add content into the Page Header field in order to get the feature to work. Here's my page:

Is there any way to configure this so it JUST shows the image, without having to add text. I was going to resort to display: none, but I feel like I'm not understanding the purpose of this feature.

Thanks, as always!
