2. Now we want to give them controls for speed and stepping
the frames. We'll also change the color of the background and foreground by
adding the parameters. Finally, we want to preserve the labels at the bottom of
each image while zooming, so we use the image_preserve parameter:
controls=startstop, speed, step, looprock, zoom
controls_tooltip = Click to start and/or stop the animation, Use the slider to adjust the animation speed, Click these to step back and forth, Click to toggle between looping and rocking, Click to enable zooming (then click mouse button on image to zoom)
filenames =TVIS1.GIF,TVIS2.GIF,TVIS3.GIF
