title: Change background position with click from a button
body: <p>Ok so im making a slot machine look alike - for this i need to make a sprite of 5 picture lets say 500 height then and 100 width (each image is 100x100). I need it so that i have a button on top of the image and one in the button og the image - so i can go to next picture with the buttom button (new position on the sprite) or previous with the top button.</p>
  
  <p>I hope someone can help me since i have been searching for something i can use all day. Im sure its very simple for some of you guys.</p>
  
  <p>thx</p>
