guys check this site hazemkhaled.com can you see the adsense block on the left? it has the site image background you can see this by scrolling down and you will see that the ad background is the website background and not a certain color well how to do this and also i want to know if its against TOS or its ok .
Never seen this before, looks cool but not sure whether its allowed or not. So avoid it until you get a reasonable answer.
well its really very good,if he change the color of the ad then it just look like part of the content,well i think he definitely be a good webmaster,he must know not to violate TOS so he applied any tool which is not common,i thnk its not against the TOS
