How to add a Google Adsense banner after my logo and blog title?

I have read many posts asking how to add additional image in the header area. However, is there a way of adding an image after the logo and title (on the same line)? My problem is... the logo and title is on the left hand of the header area and search box on the right. There's a big gap in the middle. I just want to add Google Adsense banner in there so it doesnt look so empty.

Thanks in advanced!
