The attachment seems to be a modified version that moves text around on 
the screen, not a ball.

The program uses global variables to hold the state of the moving image, 
in particular the lists that hold location and speed. Adding a second 
image while keeping the same programming style would involve a lot of 
code duplication. What I suggest is to create a Ball object that holds 
the location and speed of the ball. The movement code could also go into 
the Ball class. Get this working with one ball. Then it should be pretty 
easy to add a second ball.
