Having Problems with WIdth on Bueno Theme

Website: http://pizzaspotz.com

At the bottom of my website I now have a bar because evidently, my content is too wide. I’m not sure what happened to make it that way. I’ve determined the problem occurred after trying to add this graphic to the header area to the right of the site description, but before that, I had added it above the categories section above the black bar.

The only other thing I did around the time of noticing this problem, was adding adding this page.

In trying to fix the problem, thinking I had messed up the header code, I copied the header code from another website on which I use the Bueno theme and replaced the text on my messed up site (pizzaspotz.com).

After doing so, the width was still messed up. Of course, I went back and inserted the original header code when I saw nothing had changed.

Sorry for the long explanation, but I want to make sure I don’t leave out any information.

Thanks for any help you can provide.
