put the following in an announcement widget to make a Noodle Slide Show:

<script>
function SlideShow(){
this.pages=null;
this.page=null;
this.timer=null;
this.ms_to_show_slide=null;
this.init=function(ms){
this.pages=new Array();
this.pages[0]="/OpenFolder.po?folder=2490";
this.pages[1]="/OpenFolder.po?folder=18777264";
this.pages[2]="/OpenFolder.po?folder=18782612";
this.page=0;
this.ms_to_show_slide=60000;
};
this.next=function(){
if(this.page&gt;=(this.pages.length-1)){
this.page=0;
}else{
this.page++;
}
top.document.getElementById("main").src=this.pages[this.page];
};
this.start=function(){
if(top.noodle.slideShow.timer!=null){
alert("The slide show is already running");
}
top.document.getElementById("body").rows="0,0,*";
top.document.getElementById("lowerBody").cols="0,*";
top.noodle.slideShow.timer=top.setInterval("top.noodle.slideShow.next();", top.noodle.slideShow.ms_to_show_slide);
};
this.stop=function(){
if(top.noodle.slideShow.timer==null){
alert("The slide show was not running");
}
top.document.getElementById("body").rows="55,0,*";
top.document.getElementById("lowerBody").cols="220,*";
top.clearInterval(top.noodle.slideShow.timer);
top.noodle.slideShow.timer=null;
};
this.init();
}
top.noodle.slideShow=new SlideShow();
</script>
<input type="button" onclick="top.noodle.slideShow.start();" value="start">
<input type="button" onclick="top.noodle.slideShow.stop();" value="stop">

You can add as many pages as you want just make sure the folder ids are valid and the indexes are sequential from 0.
In the following example the index is 0 and the folder id is 2490.

this.pages[0]="/OpenFolder.po?folder=2490";

you could use any URL as a page

this.pages[1]="http://wwww.google.com";
