save it to My Pictures on you computer by right clicking and choosing “Save As”
After you have saved it go to you desktop or Start Button and open Control Panel
In Control Panel select the icon for Display
After that opens you should get a dialog box that has display properties with tabs.

In that tab you can change your background.
To find your picture and use it, you need to click the “Browse” button.
find the picture in My Pictures or wherever you saved it.
you may need to tell it “all image files” to see a .jpg
select it and hit okay and close your control panel.
now minimize all applications and see if it is set as your background
this is for Windows XP but other versions have a similar process.
I did it with my mouse with two clicks!
