Can someone help me fit this on my screen? :)

[TheLovatScout]

Sorry for being a total noob. I've even brought this image into photoshop and messed with the sizing.

The thing is, it's already big enough to be on the screen, but for some reason it keeps making the image "Tiled" instead of "Centered." I'm running EnergyROM by the way (if it makes a difference).

They made it for the iphone though

Any help is much appreciated, either tweak it or even show ME how to make it fit on my screen! anything, lol. thanks!
