Photo Enhacement
Once the photo is enlarged on your PC, you will notice a popup display in the upper right of the photo - ignore it, and, if you hover the pointer over the enlarged photo, an icon appears in the lower right of the photo that resembles a cheesburger with arrows pointing in four different directions. Don't ask me what the icon is supposed to signify, or resemble, just clik on it, and bingo - (presto?) the photo will enlarge to the largest scale, in most cases covering your screen. Use it as a desktop background, or just to get a closer look, whatever. JUST DO IT!
