Instructions: Choose a size for your wallpaper. 1024x768 is larger. 800x600 is smaller. If you're on a PC using IE, right click on the photo and choose "set as wallpaper" or "set as background." If you're on Netscape, c'mon already. Switch to IE. If you're on a Mac, click on the photo and save it to your desktop. Then hold down the CTRL button and click anywhere on your desktop. From the pop-up menu, choose "change desktop background." From the appearance menu, choose "place picture." Choose the image you just downloaded and hit "set desktop." If none of these options work, just look at the pretty picture here. Please don't email for help. Thanks!
