The Lite version of the Rollover Effect Coder can only handle very basic rollover effects, such as changing one image to another on rollover. The Pro version has been completely re-designed and features vastly improved capabilities and a new dynamic interface. With the Pro version, you can:

Create Animated Rollovers:
Add/remove any number of frames, manually specify inter-frame delay times, and specify images for each.

Apply Dynamic Effects:
Internet Explorer 5.5 includes a dynamic visual filter engine that the Pro Coder supports. Create animated drop shadows, adjust alpha blending (opacity) on each frame, and toggle images between color and grayscale.

Easily Create Multiple Effects:
The Pro Coder is designed to generate efficient source code that uses a naming scheme that shouldn't conflict with other code or other rollover effects on the same page. So all you have to worry about is experimenting and copying-and-pasting.

In this example, 10 images are used to animate a metal logo being "built". Notice how the animation starts to "build" on rollover and "unbuilds" back to nothing on rollout. It will only "unanimate" as much as was "animated" while the cursor was over the button:
· metal logo

These examples use dynamic effects specific to Internet Explorer 5.5, so they won't animate in other browsers such as Netscape. However, no preloading is necessary with these, so they are very efficient:
· fade pulse
· pop out
· bouncing logos

Here's a vague idea of the options available to you when building an animated rollover with the Pro Coder:
