I notice that you're not specifiying exactly what the link from the image is. Your best bet is to have the link go, not to the target site, but to a "click-through server" that will log the click and its originating page and then redirect to the actual destination.
You are absolutely right! A little more research reveals that the link should actually be to the ad serving CGI... which then spits out a "Location: \n\n" header after doing the logging. This means it ought to work just fine with Zope as long as we make the CGI requests not get "intercepted" by a Zope server.
