  // Customize your photo shuffle settings
  // 
  // * Surround the target <img /> with an anchor <a> and <div>. 
  //   specify unique id= in all three
  // * The first and final photo displayed is in the html <img> tag
  // * The image array contains paths to photos you want in the rotation. 
  //   If you want the first photo in the rotation, then it's best to
  //   put it as the final array image.  All photos must be same dimension
  // * The Href array contains the link you want associated with each image
  //   each image must have a corresponding link.
  // * The rotations variable specifies how many times to repeat array.
  //   images. zero is a valid rotation value.
