morphing

How can I resize an animated gif image which is composed of four different images. The resize should not effect the clarity of the image if possible. What is morphing and how can I manage to morph Schwarzenegger's body and replace it with my face in place of his face and the final thing...

Hi tried some tools for image morphing but i am not satisfied. I,ve tried morpheus,bitmorph,winmorph. Which is the best image morphing tool. Is there a plugin for Adobe photoshop for image morphing???
