AdRotator(For Advertisements):
This is useful when you want to have an Ad Banner to switch between advertisements in a round-robin fashion. When you click on the Advertisement, it will take you to the  corresponding website.Eg: In the following example, there are 3 advertisements(this is only an example). See how it works !

Complete Source Code is given below. To use it, all you have to do is : 
<1> Insert the source code given below into your HTML file between your <body> and </body> tags

<2> Decide how many Advertisements you may have and change the following line accordingly: 
var AdTotals= 3;
You may want to change the delay between Ads by changing the following line: 
var AdDelay= 5000;

<3> Change the following lines in the code. Use your image files and destination URL’s. 
AdsArray[1]= new AddImage("1200","50","imagefile1.gif","","0") 
AdsArray[2]= new AddImage("1200","50","imagefile2.gif","","0") 
AdsArray[3]= new AddImage("1200","50","imagefile3.gif","","0")<4> Change the following line. 
imgSRC="../logo.gif" to imgSRC="imagefile1.gif(your first image in the array)<a href="javascript:JumpToAd();"><imgSRC="../logo.gif" WIDTH=300 HEIGHT=50 NAME="AdBanner" BORDER=0> </a>

Good Luck !
