I've done it through My Heritage with mixed results. The software didn't recognize the faces on some of the smaller images I tried to upload, and it kind of tried to "prettify" my Italian Nona, who was a tough looking, swarthy, not traditionally attractive woman, so the animated version, which made her look lighter skinned and less heavy, didn't really look like her. Surprisingly, the one I had the best results with was a charcoal drawing of my great grandfather - not a photo at all.
One piece of advice - don't try to animate a picture of someone you knew looking the way that they did when you knew them. It's a bit less creepy if you see them as they looked before you knew them.
Oh, and I wasn't thrilled with the results of the free trial, so I didn't take out a subscription, and a week or so later, I got an email letting me animate 5 more photos.
