You'll need something like Irfanview (http://www.irfanview.com) which is freeware. Load the before and after pictures into the workspace then save the result as one picture.
Or ......... launch the before and after pictures onto your desktop then use a screen capture software to capture both pictures as one. If you're using Firefox as your browser there's an addon called Lightshot which takes screen captures.
