adding images to adsense

[funguru]

vangogh... i have started to see a rise in the click and now they are near what they were before the images but still less. I want to remove the line as well but dont want to get banned as google still has not paid me for last months revenue, and of what i have read, good wont pay anything if they ban someone. i may experiment a little more when i get paid. right now i am looking for a appropriate single image.. something like seobook had but a girl with less cloths i think that should do the trick.

Real data :

i compared both channels (same number of impresseiosn) and here is the conclusion.

by adding images to ads.

Click: increased by 40% (I am not kidding)
Page CTR: increased by 1.1%
Page CPM: Dropped by 17%
Earnings: Dropped by 35%

The only difference was that my current ad format with images is 250*250 and before that i was using 336*280

What could be the reason?
