Change Header Size & Image

Hi rafael. Give this a try:
1. In Theme Options > Styling set the Boxed Layout to ON.
2. Set your header image width the same as your Theme Options > Styling > Website Max-width.

Thanks a lot! The #1 works fine.

The #2 I still get a problem. I make a banner 1380px as the Website Max-width, but when I upload it, it′s become smaller.

I Solve it. I was doing wrong. Thanks a lot!
