EverlightBox has a very social attitude: users can comment the image they’re currently seeing.

EverlightBox is a very fast and safe lightbox for WordPress. It can be used with WordPress galleries like:
<ul>
<li>WordPress native galleries</li>
<li><a href="https://wordpress.org/plugins/final-tiles-grid-gallery-lite/" rel="ugc">Final Tiles Gallery</a></li>
<li><a href="https://wordpress.org/plugins/photoblocks-grid-gallery/" rel="ugc">PhotoBlocks Grid Gallery</a></li>
</ul>
and any linked image. You can even activate it using custom CSS selectors, so it’s virtually compatible with every gallery plugin.
EverlightBox is also a perfect solution for mobile devices, it supports swipe gestures so users are able to browse your images in a more natural way.
All users are welcome to propose new features, enhancements and bug fixes.
