Logo Area

Hi,
I have been creating a website with this theme, and recently I have run into some issues that I haven’t been able to solve on my own.

I put up a logo for my site and I believe the logo space is overshadowing the the buttons I have on the menu. The logo space is 960px long, and it overlaps the buttons I had placed on the site previously (home, gallery, etc.). Is there anyway to solve this problem or limit the size of the logo space??

Any help would be greatly appreciated
