Solve:I downloaded the following image: soccerball.jpg but I it will not load in as a sprite. 
Why NOT?                         

 It doesn't load in as a sprite because Pivot doesn't take .jpg images, only .gif and .png I believe.

I want the animation dimensions to be Width 900 Height 450 then loaded a background image: height 200 width 200.

This warning pops up: 

What happens when I choose Yes?

When I choose yes, I width and height would change the size of the animation.

What happens if I choose NO?

If I choose no, the dimensions would not change, and the image would be larger than the background.
