Adsense Text Ads with Tiny Images?

I was converting one of my static websites to WordPress this morning and came across an Adsense ad that looked like this:

Adsense Text Ads Features Images

It’s a combination of text and image, just like Chitika used to be (or still is). Long ago I heard that Adsense has tested this at one point of time (before Chitika) but when CTR skyrocketed they have stopped this test. After this they updated their polices to prohibit placing images near their ads. I find it very interesting that they are testing this again.
