I really, really hate not having a wallpaper that doesn't fill up my desktop, or that I have to "stretch" (thus making it get all ugly and pixelated), or that I have to tile. I always drop something I like into Photoshop and resize it until the resolution is exactly that of my screen's.
This is one of my exceptions. I liked the "filmstrip" look that having a top and bottom edge gave this image.
Ignore the sticky notes. They're my daily reminders of things I need to do.
