Onetone options > home page > section 1 > Section Background

I can try to modify this section but without results

/* * 4.3 home section banner */
.section-banner { THIS SECTION
}

the problem is the image resize when change the browser resolution, if i see under iphone i see a little portion of the image and not the resize complete image.

Sorry for my bad english and thanks in advance.
