Hi, I don’t know why the map is not displayed. Here are some possibilities:
1) Apple cannot resolve the coordinates to a place
2) something about maps itself (maybe a privacy setting).
If you want to email a picture to me to look at, I can see if it has to do with the file. To do that, email firstname.lastname@example.org. I recommend mailing a zip file rather than sending the image directly through the mail program.
