You should now see a window with the title “Display Properties.” To change the desktop image, you’ll want the second tab from the left: “Desktop.” Go ahead and click on it.
Now the window will display your current desktop image on the top. On the lower-left, you’ll see a selection of existing images from which to choose. Go ahead and click on any of the list to see if you find anything you like. You’ll also see some options on the right. The option that says “Color” is what your desktop will display if there’s no image. You can change that if you like. As for “Position,” there are three options: Center, Tile, and Stretch. Center places your image in the center of the desktop at its actual size. Stretch also places your image in the center, but if it isn't the same size as your screen, it stretches the image until it fills your desktop. This can distort some images. Tile places your image in the upper left corner of the screen and then repeats it both across and down until it fills the screen. If you have an image on your computer that you want to use for the desktop image, you can click on “Browse” to search for a picture file.
After you’ve found an image you like, you can preview it by clicking on “Apply.” You can do this with as many images as needed to help you pick the desktop picture you want. After you’ve found one you like, save the changes by clicking on “OK.” If you don’t like any of the images, click on “Cancel” and it will revert to your original desktop image.
