I'd love a format with like this. It would make the ad's a little less boring and bring some life and clicks back into our outdated ad's. I don't think any changes to the ad's have been made in years.
The advertiser/adwords user can upload the thumbnail they'd like to use. It will improve CTR's. Facebook has begun doing this. And of course the publisher could opt in our out of them.
Does Google still read this forum? Does anyone else think this is a good idea? Isn't time we see a new feature/format? User's have gotten so used to the old ad's no one's clicking any more. I wish Google would stay a little fresher.
