You can put images, but be carefull not to misrepresent..

Who said they are not replying emails? They do reply, and it’s fast. I have both an email about images and copyright infringement replied within 1-2 days.

Regarding the images above or or next to the ads, Google say;

it truly depends on the
circumstances of each implementation. In some instances, images may be
placed above the ads without any harm.

But webmasters must be aware of this;

there is also the possibility of attributing “undue attention” to
the ads if the images placed next to ads are misleading or seem to be
directly associated with the advertisers and their offerings

and this;

Drawing undue attention to ads is in
violation of our program policies, so we are unable to sanction every
instance of this implementation.

Google strongly encourage webmasters to maintain a visible border around the ad units to reduce the possibility of confusing users.

Btw, AdsenseBits is a place you can search those related support emails from Google Adsense support.
