"Background Image behind ads" - against TOS??? like this and if anyone contacted adsense support for this issue , I hope you post their reply Thanks
I'm pretty certain that is again the ToS. But it's probably a gray zoon. As for your best, I'd suggest you to ask Adsense. Send them that image and ask if they would be fine with it.
Well I think it is not allowed and its against the TOS of adsense. by doing this u are attracting the visitors to the ads... google doesn't allow u to do this.
This issued already been discussed before and this totally against the TOS of adsense. Avoid it or banned your account
