NGFB was written specifically to support features of NextGEN Gallery v1 and v2. These include the following:
- Image IDs from NextGEN Gallery for custom and default images in the plugin settings.
- Featured images from NextGEN Gallery v1.x (that have an image ID in the form of ‘ngg-##’).
- Gallery shortcodes (nggalbum, album, nggallery, nggtags) for the Open Graph and Gallery Twitter Card meta tags.
- SinglePic shortcode for the Open Graph and Large Image Summary Twitter Card meta tags.
- NextGEN Gallery ImageBrowser for the Open Graph and Photo Twitter Card meta tags.
- NextGEN Gallery v1.x URL query parameters (album, gallery, pageid, pid).
- NextGEN Gallery album and gallery preview images and descriptions.
- Image tags (keywords) from NextGEN Gallery.
