How?
Dead easy.
I implemented this tactic myself yesterday on one of my
sites and my CTR has gone up 300% and it hasn't been 24hrs yet.
Needless to say I'll be spending the rest of the morning
making changes to my Adsense ads across my site network.
What is it?
Sorry can't resist a little intrigue.
It's very simple. Using the Leaderboard banner 728 x 90
I added small images/photos above each ad at 140 x 100.
These photos are broadly related to the ads and draw the
eye of the visitor to the ad. Which the ad alone maybe would
not do. Once their eye is drawn they read the ad text below
the image and they are much more likely to click.
Google already knows of this tactic and I know a number of
people have approached them via email before implementing
the images. Obviously nobody wants their account suspended.
The good news is Google are fine with it, for now at least.
Although a few warnings have gone out with regard to animated
images not being appropriate. So no flash or animated gifs!
You can view this in action on one of my sites -

You can't fail to see it at the top of the page.
Now I hope this is new information to you. If so I know it's
going to be damn useful. 
And most of all profitable!
The benefit of this over Google's own 'image ads' is,
you choose the image for one and the basic text ad appeals for
another. As I'm sure you're aware text ads work better than
image ads. This seems to work better than both separately by
combining them together, the major boost comes from you being
able to select the most relevant image to your site content.
