check out this site: http://www.wisegeek.com/what-are-replica-rims.htm they use images next to all their adsense ads. I thought this was against TOS
I think the person who operates the site is very sneaky. He has blended the ad nicely and visitors will be clicking those ads by mistake. The problem with these type of sneaky ad placement is that the eCPM will be extremely low because AdWord advertisers will not consider the site for for ad placement.
The reason is simple! You can use images next to Google adsense website but they shouldn't be in a way that will provoke your visitors to click on those ads.
I think the ads are too much blended with the contents and wait for the big G to decide on the issue...
