easy fancybox along with "Another wordpress classified plugin"

I am using easy fancybox along with “Another wordpress classified plugin”.

When a user clicks on the ad, I want it to open in a popup instead of a new page. I don’t know how to pass the url of the page here. It has a url like http://abc.com/show-ad/?id=3. I only want to pop-up the content of this page.

<img src = “http://abc.com/wp-content/uploads/2012/05/ad.png”&gt;

<div class=”fancybox-hidden”>
<div id=”InlineDivID”> “what to write here”</div>
</div>
