It's not allowed now i think. It was allowed in the past but i don't think it's allowed now, at least i would contact Adsense team before using that.
No, it's not allowed. You can't decorate your Adsense looks, by put it in a special frame with border around, or add icons to it, ... If you read the Adsense faqs and Tos, you will see they said it somewhere.
The only problem is those two images in the frame and the frame is marked as sponsored links . You have placed images beside ads. Most of the user will be tricked by this and click the link as they might think the images and ads are related and this is a clear violation so I am afraid so say that you are not allowed to do that
Be careful it is not enough value to take this risk I think if you get 1$ / day better than you get 10$ but no more. I don't see yet google not allow but be careful.
No, you are not allowed. If this site belongs to you remove the images soon or you might get banned soon.
Thanks guys. It was my site but I did not put the images on I just did a bit of editing in photo shop to show what I wanted to do
it isnt allowed. You dont need it,only if you wanna 50% ctr.If you wanna reasonable 15+ ctr put 336*280 above the fold
