These examples have their transparent masks removed, and don't tint an image when the mouse moves over it. They also show a 1-pixel border when an image is focused.
The two examples also use different alignment: the applet on the left has its Align parameter set to 'Right', and the applet on the right has Align set to 'Left'.
We've also changed the height of the invisible 'hotspot'. In the previous example it was 40 pixels, meaning that animation stopped when the mouse entered a 40-pixel-high area in the center. Here we've made the hotspot the same height as the applet, so animation stops as soon as the mouse enters. As a result, the animation never accelerates or changes direction.
