how do you combine two photos?

[photosonwheels]

I have two digital editing programs, photo explosion deluxe 2.0 and photo impact pro 8.5 I can't seem to figure out how to combine two photos into one. By this I mean perfectly outline say a person in a photo and out that person on a different photo. Can anyone help? For an example of what I am talking about please go to the link I have provided
