Remove Logo Header BKGND, to have a Full Page BKGND?

[CritiKiL]

Ok, the Xenforo has the 'Logo Background' and then the Body Background. This makes it hard for me to add a 'Full Background' without having to splice it for two areas. How do I fix it so that there's just one full complete ability for a background image? Thanks in advance ;0)
