Click the icons with the symbols to go to next 'style', click the arrows to bring that thing forward or back. Click 'done when you done and 'back' if necessary and click 'click for next backdrop. Click 'hide' in the end to hide the 'back, hide, click and done' symbols when FINISHED. Enjoy!! you can enlarge the image, but don't do it too much or it gets weird. And I am making it draggable when you press 'done' now.
Some parts are dodgy I'm sorry :)
