Adsense and Image Placement
Lately I have been seeing an increasing number of sites using AdSense and placing misleading images next to the ads. This is against their policies!
On the AdSense blog last December there was a post about this that I read and since then I have seen many, many sites using these and similar techniques that they must have learned somewhere to try and increase their click-through ratio.
"We ask that publishers not line up images and ads in a way that suggests a relationship between the images and the ads." - Ad and image placement: a policy clarification
I fear this will eventually get some peoples AdSense accounts closed so I am just posting the above link so you can check and see if your site is in danger.
