Maybe you're looking for something like Haptek where one can "paste" or apply their own image to a character's head then apply morphs , emotions, etc.?
It depends a lot on how the image is placed on the character head and some of the morphing and emotion tweaking causes the resultant image to "stretch" along the sides.
What's needed is for the program to allow one to attach Left, Front and Right images to the head then with a merge, the result might take on a more realistic appearance.
