Why you had such a loss is because your images most probably came up for unrelated topic, normally not resulting in any clicks.
Nope, I'm not going to go through all of this one again however social networking sites that pretend to provide background images were hotlinking using their own Google image searches thus when a social networker chose an image for their background, as in my full sized image, it generated both a page and AdSense impression.
I've been keeping a check on all my metrics this week since it was introduced and I have not seen any noticeable increase in bandwidth BUT I have seen an increase in both AdSense CTR by ~25% and earnings by ~11%.
If this has anything to do with the new layout I have absolutely no idea however if it continues this way I ain't going to knock it:-)
