We rarely talk about the Yahoo Directory these days, but Loren Baker at Search Engine Journal spotted Yahoo serving images near the sponsored listings within the Yahoo Directory.
For example, the NY Internet Consulting directory has tons of ads, most with images near them. Here is a screen capture.
Notice the top ad has a smaller image, and the ads on the right have slightly larger images. I have never seen Yahoo place images near sponsored ads. In fact, Yahoo specifically warned publishers to not put images near their contextual ads.
This is not the first time Yahoo placed images near their ads. They did display images near premium contextual ads in the past. But never in a search results setting, which includes directory listings.
Loren Baker explains that these images are not clickable and are hosted by worthathousandwords.com, aka. ImageAdvantage.
