There are quite a few ways of morphing photos. Here's one...
You can blend photos together..in a way so that it looks like the photo I have included..I morphed two photos of me and one photo of Scarlett Johansson to get this rather scary image hehe

Go onto www.morphthing.com...
This is free. There are other ways to do it if you have photoshop and most other photoediting programs.

The following picture shows the two pictures that are combined to make the final product

The process is called stitching, and is common to most photo workshop programs
