Step 2: Copy the entire code below and save it as "popup.htm", under the same directory as the page in Step 1. This is the page that will get loaded into the pop up window. It contains both the script required to load the target URL into the main window, plus a sample Link Exchange code. Change the LinkExchange code to your own banner's code. You can in general edit any part of the below code EXCEPT the parts in red. They should be perserved. The code onClick="loadurl(this.href);return false" should be inserted inside the tag of your banner code, like below.
