I'm trying to ad a small rotating banner ad (468x60) in place of the site description in the header area of the Twenty Ten 1.2 theme. I've tried different codes dozens of times, but the best I can get it to do is appear below my site logo on the left side. I'd like the ad to appear on the right, centered with the logo, kind of like on this site: http://www.helium.com/ and I don't need the site description to appear at all.
My site URL is: http://www.tazaaoffers.com
Please note, I'm a novice when it comes to code and WordPress, so please be as thorough as possible in your description.
