How do you find out your desktop background size?
Right click anywhere on your desktop, click Properties, then click on the settings tab. The number, also called resolution, shown here is your background size.
You can. As long as the computer can read the picture file with paint, it will work. Just right click on a blank spot on the desktop, then "Properties". Click on the "Desktop" Tab, then click "Browse". Find your picture, and click ok, then apply/ok. Also, you could go to the picture, right-clik it, then select set as desktop background. i want a picture on set as desktop background
