Is there an online photo service that will send a personal note with the photos?

I am trying to send some pictures of my daughter to my grandparents. It is a long story, but I rarely see or talk to them. In fact, it has been about 15 years. We do write from time to time.

I want to include a note about the pictures I am sending, but Snapfish, Photobucket and Walmart do not allow for this. Does anyone?
