@julies - I have experienced the same thing when it comes to Christmas photo postcards. I receive more of these any cards or letters anymore. Because they are so quick and easy to do, it also makes sending out Christmas cards much less of a chore.
I always enjoy seeing pictures of friends and family every year when I receive their photo postcards. It is a nice way to keep in touch and so easy to do with digital cameras and all the photo options we have now.
