Thanks everyone. I forgot a convenient feature of PowerPoint: the ability to save objects as native images. In other words, that new image, with the rectangle border around the original photo image is itself savable as JPG. I think all I have to do now is tell the photo people that I DO want the border to print. The effect, therefore, is to "shrink" the image, including the head.
THe question remains: when I copy an image from PowerPoint into Paint, the image deteriorates markedly. What's going on? Thanks.
If you PM me, you can send the image and I'll do it for you, assuming that the original is good quality.
