I have a site and want to put an Adsense Image Unit right below an Adsense Text unit, is it against the TOS? I can't see where it is
You cannot confuse readers that the image is directly related to the ad. For example, if your site is about iPhones, and you place iPhones right next to the text ads, then it can confuse readers to think that the link will get them to the iPhone product that is shown in the image. That is a ban right there.
You do realize i was talking about an "Adsense Image Advert" meaning it could display any image, not just an iphone.
it will be better if you can put the screenshot. if the placement are not confuse the visitor, then it should be fine
