Question

I created a slider But I am going some where wrong in my logic. I am able to show all the images, but not in an order. So initially image1 after that image2.. the sequence is going wrong in my logic.
And the image should load as we enter into the browser, it took some time to load.

here is the live demo link:

      if  ( prevIndex < maximages ){
       shuffleIndex = prevIndex;
       prevIndex++; 
      }
      else {
        prevIndex=0;
        shuffleIndex=prevIndex;
        prevIndex++;
      }
