In the section where you get to choose your page colors there's a tab for more advanced editing. Click that tab and there should be a button to browse your photos that you can add to your page background. Then you upload that picture and it should appear after you click the 'save' button at the bottom of that page.Hope this helps.
I love sunsets too, and I never get jaded about them. Spent a lot of time on the west shore savoring that time of day. It occurred to me that each day's composition was different. That we were being treated to a new work by the Master Artist every single day.
