I scanned and saved some family photos then set them as my wallpaper. Prior to this I had chosen the "DaVinci" theme for my desktop-saving some of the icons that I liked, replacing others that I didn't. That theme comes with a brownish background color as its wallpaper, and now as my computer is starting up it is there for quite a while before my pictures appear. Is that more taxing on resources than necessary? Can/should I do something to make the move to my choice of wallpaper happen more quickly?
