To apply a moving desktop background to your computer or laptop, search for a moving wallpaper from a website that has wallpaper downloads. When you find a wallpaper you like, begin the process by clicking the Download link next to the image.
Once you click on the download link, a pop-up window or new page appears asking you to choose the screen resolution that fits your computer, such as 800-by-600. Once you select the resolution, choose the folder or file where the image is saved, and start the download. Once downloaded, navigate to your Desktop to select the downloaded image. Be prepared to pay a fee for some wallpapers, or search websites for any free downloads they may have.
Another option is to use a software program to create a moving background from a screen saver, such as Vital Desktop Software. These programs allow you to save any screen saver as a moving image file that is usable for a wallpaper. Other moving wallpaper programs are designed to animate your pictures or images. Choose the type of animation you like, and apply it to the image. Some of these programs charge a fee for the animation, while others are considered freeware.
