It's exactly how dmi told (thx mate!)
The problem is that Google (and many others) just iFrame your site, which means that you won't get your share or revenue there.
If you use that Google Adsense Whitelist it surely doesn't include Google images, does it?
No, so basically you won't get any credit for any clicks that visitors make @ your site.
Using this little "trick" you'll break the frame and visitors will see your site only, instead of some iFramed version of it.
If you're using wordpress there's no need for you to edit anything, all you need is to install this plugin - Break-Out-Of-Frames WordPress Plugin - et voilá, problem solved.
