Steevler, what you need to put the face picture on a Poser model is a texture template, a flat representation of the UV coordinates of the model (Im sure 3D Max works with UV mapping as well). Ready made texture templates are available for the Poser figures, they are the starting point for the work on Photoshop. The resulting texture can then be applied to the Poser figure, and the body parts align to where they are supposed to be.
