title: Using multiple images and to display at random
body: <p>How could I make it randomize what image shows up so that there is a different one displaying every time. Here is my code, and the images I want to add to get randomized are for instance "tutorial2.png" and "tutorial3.png". Where would I add them into this line of code so that it randomizing which one is displayed. I'm not too experience either so detail and code would be appreciated, thanks.</p>
  
  <pre><code>self.help=[CCSprite spriteWithFile:@"tutorial.png"];
  self.help.position=ccp(ws.width/2,ws.height*4/4/2);
  [self addChild:self.help];
  </code></pre>
