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>

//Rotating Banner Function by Crondesign.com 2009
fadespeed=5 //speed of transition
interval=4 //seconds to wait on each image

//make duplicate of banner called bannerB:

//run the gobanner function on a loop:

//Changes the banner image:
function gobanner(){
//jump bannerB to the next frame and stop any animation:
//fade out the main banner:
if(_alpha<=0){//when fade is complete:
//stop the fade:
//jump the invisible banner to the next frame:
//and make it visible:
//jumps a MC ahead one frame on a loop:
function nextImg (mc:MovieClip){
//stops all child movie clips:
function stopChildren(mc:MovieClip){
for (var m in mc){
if (typeof(mc[m]=="movieclip")){

Hi Cron
How do I animate third frame the opposite way to how it appears on the stage at the moment (sliding into a stage and out when the next frame appears on) also how difficult would be to ad arrows < and > for manual change if needed?

Hi Natasha,
To add the internal animations on each slide you need to create a movie clip and place it on that frame. Just remember it needs to be shorter than the interval paramater or the end of the animation will be cut off.
You can simply edit the movieclip on frame 3 to animate in the opposite direction.

The < and > arrows would be a little tricky as you would need to stop the automatic Interval and restart it after the click.
