Thank you!! Lol I will tell you how I did it!! Lol
Ok so first I went into Customize My Page which is underneath your photo and info.
Then a thing will come up that will say Edit The Appearance Of Your Page will come up you go to the bottom of that page.
At the bottom there will be three options: Basic Themes, All Options and Advanced
Click on All Options
In All Options there will be Colour, Texts and Media Players
look at the Colours one and on your right hand side The one that says Body Image.
Click on the little camera that you see on Body Image and then you can go No Image or Upload Image from your computer.
Select upload from your computer choose a photo then click on it and it will got back to the previous page next to that little camera will be another thing with an arrow next to it.
Click on the arrow and it will say Don't repeat image, Tile Image, Repeat vertically and repeat horizontally you can choose any of those (like mine is tile image).
Then go down ton the bottom and click save!!
