Make the banner more little

[tu y tu mama]

Well since not everyone's screen size is like 1280 x 1024 or something like that (example: me), the image at the top that says "Rune Gear" (the banner) is bigger than 1024 and doesn't fits in my screen so I've to be scrolling to the left and right to the stuff like who was the lastest poster on X thread.
So I'm asking if someone in Management can make the image width 1024 (my screen is 1024 x 768) or make it that it auto-resizes to the screen width with a html code...

Spoiler: Image of my screen

Spoiler: A little html code

html {
background: url(images/bg_oap.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}

I used that code in my website once. Credits to: iamsuperbadim (YouTube)
