Use web pictures for desktop background
The internet is full of eye pleasing beautiful pictures. While surfing the amazing world of internet, if you hit upon a picture you particularly like, such as the following image of the Lagy Gaga, you can make it your desktop background, so that you can see it whenever you use your computer.
In Microsoft Internet Explorer, right-click on the picture and select Set as Background to set it as your wallpaper. You will immediately see the result. In Mozilla Firefox, right-click on any picture and select Set as Desktop Background to set it as your wallpaper. In Opera, right-click on any image and select Use image on Desktop to set it as your Windows' wallpaper.
Although you can use any picture you want, but for best results, you should use pictures which are wider than they are taller. If you have a normal screen monitor, then use a picture with width to height ratio roughly as 4:3. You do not have to measure the picture, just estimate by looking at the picture. If you have a wide-screen monitor, then you should pick pictures with width to height ratio of 16:9.
