Required: Genesis Framework, Prose Theme
First, determine the size of your header image. You must use a width of 940 pixels, but you can choose the height. We recommend that you use an image with a maximum height of 200 pixels, so as not to push your main content too far down the page.
Next, you must set your header height. When you determine the height you want to use, go to the Genesis > Design Settings menu. Go to the Header panel (it should be on the left column) and change the Header Height to the appropriate value. Click Save Changes.
Next, you must upload the header image. Go to the Appearance > Header menu. Here you can upload your header image. If it is larger than 940 pixels by the height you selected, you can crop the image. You can also choose whether or not to display your header text (your website title). When you are finished, click Save Changes.
