Display rating
When turned on, a rating widget will be added to every thumbnail and to the info panel in the lightbox too.
Use jAlbum's rating
The rating given by the album author in the jAlbum application will be displayed.
Allow visitor rating
Visitors can rate the pictures, and with the help of the Filtering tool, they can narrow down the selection. Useful when they select pictures for buying.
Note, these ratings given by visitors are not stored, neither synchronized between them. That would need a database running on your server, which is not so easy to implement for every user.
