in order to make a new image. I change the height to 532 pixels and the width to 400 pixels because that is the size of the picture I'm using. You should also change the size of the new image according to the image or layout you are using. Then you choose the background for you new image: click on 'gradient'. Choose the 'duotone red'- gradient. Change your settings so they match mine from the screenshot, and press ok so that your new image can be created.
