AdSense team is beta testing a new feature called "Vertical Images." There is a generic image which takes the place of an ad space within an AdSense ad unit. These images are links and lead to a page with more ads related to the topic of the ad unit. Jennifer Slegg includes a screen shot of a set of ads for florists and wedding flowers that is headed by a photo of a rose. The beta test is available to international publishers as well as to U.S. publishers.
