> it would seem if we waited long enough the image of our friends outside the event horizon would outlive the black hole and we could go say hello after it evaporated
You would see your friend's image, but your friend's image is not your friend. If you tried to go towards where the image appeared to be coming from, you would just find empty space, where the black hole that evaporated away (with your friend inside, having long before hit the singularity) used to be. Your friend would not be there any more.
Note, btw, that once you see the final image of your friend (the image of him just crossing the horizon, which you see in a big flash of light when you see the hole finally evaporate), you see nothing more; your friend, and the hole, and all of the other things that fell into the hole (and whose images as they crossed the horizon you also saw in the big flash of light) all vanish after that (no more images are coming).
