There will also be a line which specifies the height of your headerimage, I guess the current one is 300px, you'll need it to change to 533px, the height of the death by cotton pink image.
This image has the same height as your current banner so all you have to do is exchange the previous link in the CSS box with this one and save the change^^

Then you go to Custom CSS
Under Custom external stylesheet URL is a box
