Good morning, I have installed zenphoto for some time and now I would like to give my visitors the possibility to vote for the photos, can you tell me a plugin for this.
Thank you very much

There is a rating plugin included.

Excuse me acrylian, I'm a novice at this, can you tell me the route to access it.
Thank you very much.

Find the plugins tab on the backend and enable it. Official themes should support it, for others you might have to modify the theme.

Thanks acrylian, I've already found it in Extensions, now I have to learn how to configure it.
