Office 2010 doesnt Scan , a Scanner does.
Office 2010 doesnt Edit Pictures , A seperate Program will , eg: Photoshop , MS Paint , Corel , Gimp.
Opening any file to edit , once done you should select " Save As " and rename it , then the Original would stay intact / or as it was.
If you just select "Save" it will Prompt you to Overwrite the original = y/n.
You have to be more clearer what your friend is trying to do , or yourself in explaining the actual problem your having , or what you need to achieve.
