I'm sorry Craft40, but I'm not sure of what you are wanting. Are you wanting to create your own themepack that includeds your background image? If so, then this may help. After creating your theme, save it as a themepack. When you run the themepack on any Windows 7 computer, it will install that theme completely.
Build 7100 will not work with this though.
