This basic plugin enables the Magnific Popup image lightbox to work with single images within your posts and pages, gallery images using the built-in WordPress gallery and also WooCommerce product images. 
Images within a Gallery will have next and previous arrows. 
You can add an alt attribute to your image, to enable lightbox ‘captions’.
The plugin comes with a Settings page for you to choose options. All are off by default.
Thanks to Dmitry Semenov for the original script and hard work: http://dimsemenov.com/plugins/magnific-popup/
Note: This only supports images and not the full capabilities of Magnific Popup.

Simply put, this plugin works great but could slightly be improved :)
I would love to get in touch with the developer and submit a pull request to improve a few things...
