Free AS2 Script for Rotating Website Banner or Slideshow in Flash

This is a simple AS2 function to turn a normal flash MovieClip into a rotating banner or fading photo slideshow for a website. Timings and speeds are customisable, it works with any size images and will even work with animated content. All you have to do is put one photo on each frame of a Movie clip and the script does the rest.
Full instructions and demo below...

1. Make a Movie Clip on the stage containing one photo* on each frame. Add as many as you like but there must be one on every frame in the MC for it to work correctly.
2. In the properties panel, label the instance "banner"
3. Copy the code below onto the same frame as the banner clip
   
   * alternatively you can create a new movie clip some of the frames and do a little animation inside it.

 Please see right hand panel before copying>
