Change your login screen wallpaper image

Sometimes default things get old real fast. We look at them long enough and they start becoming eyesores. This also seems to happen with ever single design project I work on — I start out loving it, and by the time I’m finishing up — I hate it. It’s a disease, and I’m working through it.
