title: How to change the size of an image?
body: <p>I am creating a game of space invaders and i would like for all of the images to be in ratio to the screen resolution. This means that it can be used on all screen sizes and all the images will shrink or get bigger so that they fit onto the screen. The game is fullscreen. What is the easiest technique to do this? Also is this the best way to set the size of everything? </p>
