THREE–D, Rectangles, and Images
Rectangles and images do not automatically acquire three-dimensional characteristics when you specify THREE–D for a frame. Rectangles must have border widths of two or more pixels to display in a three-dimensional style. Images are completely unaffected by THREE–D. This avoids any indication that you can interact with them. If you want, you can achieve three-dimensional effects for an image by displaying it on an appropriate rectangle or by including the effects within the image itself.
