@EducatedSavage: ok I see your site and now I understand your question. You have to make your featured image in pages to be your header image just like in homepage. For that, just go to “Appearance => Customize => Header Image”. Then in “Enable Featured Header Image on”, you need to choose the option “Entire Site, Page/Post Featured Image”. Finally click on save and publish.
Then, you can disable your current page image that is there below promotion headline For that go to “Appearance => Customize => Theme Options => Layout Options” , then in “Single Page/Post Image Layout”, you need to choose the option “Disabled”. Finally click on save and publish.
