By default Mac OS 8 installs a folder called Sample Desktop Pictures in the Apple Extras folder on your hard drive. After downloading your Wallpaper selection, place the file in the Sample Desktop Pictures folder. The Desktop Picture Control Panel allows you to select and activate the Wallpaper image that you have downloaded. To get to the Desktop Picture Control Panel look under the Apple inside the Control Panel folder. Within the Desktop Picture Control Panel click the "Picture" button and then click the "Add Picture/Remove Picture" button to make a selection (pick the image you just downloaded.) Click the "Set Desktop" button and you're done!
