How to Place an Ad Inside a Flash SWF?

I have a site with a simple SWF that shows a series of frames for a cartoon each time the 'next' button is clicked. At the last frame I want to place a space for an ad such as Google Adsense. Is there a way to insert the Adsense code inside the Flash SWF so that it only displays on a particular frame?

Thanks!

Google Adsense is actually some HTML codes on webpage. You can check the HTML Ad Plugin of playerDIY that can add HTML ad, such as Google Adsense inside or over flash video player - http://www.playerdiy.com/configurati...s/html-ad.html
