This add-on extends the functionality of the free NextGEN Gallery Voting plugin with a couple of great new features.
For starters, it adds a new voting option of a plain ‘Like’. This ‘Like’ voting type works in the same say as the ‘Like/Dislike’ available with NGGV Free, but without the ‘Dislike’ option. This allows you to offer Facebook style ‘liking’ of galleries and images.
You can also change the image used to perform the ‘like’ with a simple file upload.
This add-on also adds the ability to edit the messages your users see during the voting process. For example, you can change the term ‘Like’, to ‘Vote’.
You can also now update all your exiting gallery and image options with a single click.
Please note, this plugin requires NextGEN Gallery voting 2.2 or later to be installed, which is available for free from http://wordpress.org/extend/plugins/nextgen-gallery-voting/
