ok. here is how it works.
if someone likes or someone posts a comment you will get and email like. ...
Your photo has just been liked
The email will include the photo and a link to the photo that was just liked.
if a comment was posted
the same will happen with a link to the photo. clicking on the link will show you the photos and comments for it.
I will work opn making this better.
One note,
if someone posts a comment or a like then they reverse their action, the email would have gone out before the reversal of thier action. so that could be a buit misleading.
