NextGEN Gallery, with 1.3 million active users, is the defacto standard for managing WordPress galleries, and combines with NextGEN Pro to offer gorgeous gallery displays, full screen lightboxes, commenting and social sharing for photographs, proofing, digital downloads, ecommerce, and more. And everything comes with fanatical support so you can spend less time on your website and more on your photography.
NextGEN Pro customers now have the ability to add captions above or below Pro Blog Style Galleries. In addition, they can now add hover features to multiple Pro gallery styles. Hover capability includes options to display social sharing buttons, photo titles and descriptions. A new minor, but useful feature is Twitter Card support for social sharing. Last, but not least, the new feature includes retina support for thumbnails, which will allow small thumbnails to look more clearly on modern displays.
