Seems like Google is testing a new UI for images, as you can see from the image above, there is a different layout that pops up. As stated in WebmasterWorld, yeah it is incredible and great for Google, they are using showing someone else’s image as the image only pops up in the a layer but the webmaster of the site is not getting any hits from it, only Google is. So it pretty much looks like and is good for Google and possibly the person searching, but not the webmaster who provided the image.
