// * set background-repeat:no-repeat in CSS for the div
// * The first and final photo displayed is in the html <img> tag
// * The 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 rotations variable specifies how many times to repeat array.
