Background Graphic for gaming website

I need a background to hug both sides of my website, the same way [login to view URL] has. I need this image to be exactly 1734px Wide By 676px High. This image will have Black in the middle, and graphics on both sides, just like some popular online gaming sites. The image will fade to black on the bottom to blend in with the black background properties. The images must be game related, and must include: world of warcraft, aion online, halo odst, The Darkness(something creative with the darkness snakes), or a number of games from Xbox, or Playstation consoles. No Nintendo characters please. Sample image layout is included in attachment.
