Unfortunately Windows only gives you the limited options of center or tile for the placement of the desktop wallpaper.

With this setting you can move the image anyway on your desktop:

1. To open the Registry Editor click on the Start button on your taskbar, then click on Run and type "regedit" and click on OK to start the utility.
    
2. Expand HKEY_CURRENT_USER\Control Panel\Desktop (see picture 1).

3. Create two new STRING values of "Wallpaperoriginx" and "Wallpaperoriginy". If the values already exist then you simply modify them.
    
4. Set the value of "Wallpaperoriginx" to equal the horizontal offset, and set the value of '"Wallpaperoriginy" to equal the vertical offset.
    
5. The modifications you made will be in effect after you reboot your PC.

Note: The image is offset from the center of your desktop, so you can use positive and negative values.
