How do I use these desktop pictures on my Mac / PC?

Before you use any of the desktop pictures, you must decide which size image to preview and save to your hard drive. If you don't know the current size of your monitor, check the Monitors Control panel on a Macintosh or the Displays control panel on a Windows computer. Typical screen resolutions are 800 x 600 pixels, 1024 x 768, and 1280 x 1024. Choose the pixel dimensions that are closest to your current monitor setting.

Macintosh

To use desktop pictures on the Mac, find and open the appearance control panel in your system folder. Click on the "Desktop" tab to display the current list of installed textures. Click the small preview of your desktop to make the pictures button active. Click the Place Picture... button to select your desktop picture. Click the Set Desktop button to apply the new picture to the desktop.

Windows

On the PC, click on the Start menu, navigate to Settings and then to Control Panels. Open the "Displays" control panel by double clicking it. Select the "Background" tab and click the Browse button. Locate the picture you downloaded and select it. Make sure the Display pull down menu at the bottom of the window is set to "Center" and click the Apply button.
