A trick you probably don't know- Windows 7 - how to find ALL of
   the picture on your computer:

   Start: ''Computer''

   On the search bar to the top-right type kind:

   You should see a drop down to various kinds of search - choose
   the one you want and hit enter

   If you want to find all pictures, the search would be
   kind:=picture

   If you want to search for pictures and something else then it
   would be kind:=music OR kind:=pictures OR kind:=videos
