title: Tapku Coverflow: Programmatically change image
body: <p>i'm trying to implement a button to increment the album art using Tapku Library and not having much luck. </p>
  
  <p>I was considering replicating a touch using 'touchesBegan' but this is a bit hacky and would rather a cleaner approach. </p>
  
  <p>My code to increment the image, which does not update the image is as follows:</p>
  
  <pre><code>(IBAction)nextImage:(id)sender {
      if(imageSelected++ &lt; kNumberOfImages){
          coverView.image = [imagesArray objectAtIndex:imageSelected];
      [self coverflowView:coverFlow coverAtIndexWasBroughtToFront:imageSelected];
      }else{
          imageSelected--;
      }
  }
  </code></pre>
  
  <p>Can anyone tell me where i might be going wrong? Thanks</p>
