Hi ! ! ! !

I had posted in oDesk looking for a Graphics Designer. I posted that I needed an Background Image for my WordPress Body, not Header. But for some reason they keep thinking I am wanting a Header Background.

Maybe I am asking the wrong question. Can someone please tell me how I may get my point across?

This is what I want. I want an Image, one that sits Top Center that spans the whole width of the page. I want it to be 320px in height. My wrapper is 906px in width. I mean am I saying it all wrong?
