You can credit me if you want but it isn't necessary. Besides, I am not sure how you would do that for the page background.

Just knowing the "length" of your screen doesn't help. The 24 is measured from one corner to the opposite corner so it doesn't tell us how tall your screen actually is. The best I can do is reduce the image's aspect ration and hope that it fills the height on your screen.
