Add Pinterest to the NextGEN Gallery plugin.
With over 10 million downloads the NextGEN Gallery plugin is obviously widely used. The Pinterest Lightbox plugin enables a PinIt Button on each image automatically through your NextGEN Gallery. It automatically uses the caption, image URL, and page URL from NextGEN to sync with the Pinterest API. This plugin is very useful for photo-intensive websites.
To use it, simply download, and activate. Please note NextGEN 2.0 or greater is required with the latest update of Pinterest Lightbox 1.4. Pinterest Lightbox now supports all NextGen lightboxes, so you can pick and choose which one you want to use directly from NextGEN. If you do not have NextGEN installed, the plugin will display a notice and do nothing until it is installed.
