4. Click on edit photo
5. Tick "This image is : A profile theme image
6. Then click on the profile theme link.
You will see various pre-designed themes already, but as far a I can work out you can only design your own theme with a background image, I haven't worked out how to change text colours, backgrounds etc for your own theme.
