NGG Voting was inspired by a request from Troy Schlegel of Schlegel Photography. Please read the FAQ for more info on how it works.
If you want even more features and functionality, be sure to check out the <a href="http://codecanyon.net/item/nextgen-gallery-voting-premium/3307807?ref=shaunalberts" rel="nofollow ugc">Premium add-on</a>.
Please read the FAQ, as you are required to add a tag to gallery templates for certain functionality to work!
<h3>No Longer Supported</h3>
Please note: Due to some personal life circumstances, I was unable to provide the support level I wanted and this plugin stopped being updated awhile ago. 
Bringing this plugin up to date, and improving its usability are not feasible, so it will not be updated in the future.
<h4>New Replacement Plugin</h4>
I have released a replacement plugin that drastically simlifies the user experience, requiring no editing of templates, or code changes. 
I will be updating the new ratings plugin with features, and providing active support. Please check <a href="https://nextgen-gallery-ratings.shauno.co.za/" rel="nofollow ugc">it out here</a>.
