To set a picture as your wallpaper, just right click on the picture, and then click on "Set Picture as Wallpaper". However, there is a possibility that the pictures will not align correctly with your desktop. In that case, click on Start, Settings, Control Panel, then click on the Background tab. To tile a small picture, select the Tiled option on the display drop-down box options on that same tab. To make a picture that is larger than screen into wallpaper click on the Stretch option on the display drop-down box. To simply center a smaller picture, just click on the Center option.

To save other pictures that can be later set as the wallpaper without visiting the BVFC then right click on the ones you might want to use later and click on "Save Picture As…" Later, if you want to change your wallpaper, simply go to Start, Settings, Control Panel, and click on the Background tab. To select the next background, just click on browse and then find the filename which you saved the picture as.
