It's laughingly simple, yet the effect can be immediate.
All you need is to get some colorful digital photographs, either from your own stock or from a royalty free web site. Then using a graphics program, such as Real Draw PRO or Photoshop, create a strip of four rectangular photographs with a space in between each. The overall size of the strip should be 728 pixels wide by about 108 pixels deep. The size of the pictures should be about 140 pixels wide by whatever depth you choose for the picture strip.
The content of the pictures should be relevant to the content of your web site. In order not to violate Google's Terms Of Service, you should avoid pictures that are animated, advertisements or induce the visitor to click on the AdSense ads. If you are in any doubt, take a look at the ads on my web site or check with Google's Terms Of Service.
The background color should exactly match the color of your AdSense pages. It helps if you can place a narrow blue border around the individual photo (but not around the entire strip). This arrangement is ideal for a page containing an article and the best position within the page for the picture strip is at the top of the page, immediately below the page headline, but above the start of the body text.
Once you have done this, go to your Google AdSense advert codes and select the one for leaderboard, which is 728 pixels wide by 90 pixels deep. If the 728 pixel width sounds vaguely familiar, it's the exact width of your picture strip. Make sure you delete the border before pasting your leaderboard code under the picture strip, save the page and load it to your server and start enjoying up to three times the clicks on that style of ad.
If you already have the maximum number of three AdSense blocks on the pages, where you insert this picture strip/leaderboard combo, do be sure to delete one of the existing ad groups, so you don't violate Google's Terms Of Service, which only allow three ad blocks per page.
