I suspect this will help me spot cloaking unless it's some other bot agent generating these.
I also noticed on one of my sites they showed a blank spot where I had an embedded youtube video.
People using bigger images will get a lift from this I think.
On the other hand, I'm finding myself browsing the SERPS using these and passing over a lot of sites that before I would just click on and look at. That's going to reduce traffic, but it should improve the quality of traffic since I won't be hopping on and off those sites in three seconds.
