No, I will not be adding new backgrounds each day. These images are from the website http://antwrp.gsfc.nasa.gov/apod/astropix.html which is updated daily. However, I have only taken the ones that I liked and turned them into backgrounds through the regular process of resizing, cropping, and the like.
