No you cant any way divert the visitors the visitors to click on the ads.
Also many people have sites with Images next to them
The 4 Images ads placement works the Best
No you cant put ads next to any google ads. Bad ethics. I do believe that google would ask you to move the ad. All ads must be seperate and placed strategically in places seperate from each other.
I do know you can have google and clicksor but not on the same page on your site. You can place google on your front page and clicksor in your forums.
