How would you handle a background image for a web page with a curve like the one below? Normally, I take a thin image and repeat it along the x-axis, but the curve negates that strategy as one side is lower than the other. Ideally, I'd like to have the lines continue along their current path (even on larger monitors) without having to use a huge image for the whole thing. Any tricks or suggestions to do this in a way that doesn't kill my page size?
