This simple app shows an Image Switcher with Zoo Critter clip art.
The user simply clicks the 'NEXT' button which loads up the first Zoo Critter that happens to be a Gator. Then they can flip through the other host of animal characters. But they also have the option at any time to go back an image or two or more depending on how far back they want to go by clicking the 'PREV' button. Examples of all the images going forward using the 'NEXT' button are shown below with a few using the 'PREV' button.
