I remember years ago a company called widgetbucks which i wish still existed. Basically you would have an ad with a heap of products that you could scroll through. Say the top phones with price and buy now. Has anyone seen these types of ads on adsense at some particular size?

Im also considering using image overlay ads from another advertising network, anyone know of one that accepts small images rather than bigger ones? My site only has thumbnails that link off to the full sized image and last i knew ads cant appear on images that arent on a page.
