What Is High Resolution Digital File? When you choose the High Resolution Digital File option, Your JPEG image(s) (1-2 megabytes per image) will be burned to CD and sent to you via U.S. Mail. The image resolution is good enough to enlarge to 16x20 inches in size, and in some cases up to 20x30 inches. In addition to being ideal for printing your own photos in any size, they make great screen savers, and you can also e-mail them to your friends and family to show them how much fun you had here at Snowbird!
