70 * - It displays two animated images, an animated dog and an animated DALi logo.
71 * - The images are loaded paused, a play button is overlayed on top of the images to play the animated image.
72 * - Radio buttons at the bottom allow the user to change between Animated Images and a collection of Image Arrays.
