W:
Why not just get a bunch of image with faces in them and then trace
around the face in Photoshop and copy the face. Then paste the face
onto a standard background image of your choosing (it will be in a new
"layer"). Then "flatten" the image (to combine the layers into a
single image) and save it out. Photoshop even has controls for
running it as a batch process. I think this is a good way to create
your test images.
