Thanks for working on this. The ability for visitors to change their rating back to zero (unrated) works fine.
I am, however, struggling with the "Use JAlbum Rating" feature. I've created albums with this ON and also turned OFF. In both cases, it pulls the rating from my original images rather and creating an album where every picture is unrated when it is opened. I've tried it with both linked and copied images and get the same results. Am I don't something wrong?
