The image used in the Mass Effect wiki has their background theme design not set to fixed, and their image has a gradient to "face to black" below the main image to make it look like what you see.

Ours is set to fixed and tiled, so it moves as you scroll and repeats itself when the resolution of a user is too large for one image to take it all in. A non-tiled background in higher resolutions should look like this.

Basically I just wanted to make the image a bit larger, while having a gradient to fade to whatever background color is set to the upper, left, and right edges of the image so that screens in higher resolutions will not be having this problem. What I see is technically this.
