My users are logged on, they set notify to Yes during the upload, but still nothing happens. The entry is not going into the notification table.
If they click on "Receive Email Updates" under any desired photo then it works OK - that must be entering into the notification table correctly.
For some reason that I would dearly like to discover, the entry is not being made into the notify table during the upload, even with the Yes selection made. Many users are reporting this.
