<a href="http://fancybox.net/" rel="nofollow ugc">Fancybox</a> is a tool for displaying images, html content and multi-media 
in a Mac-style “lightbox” that floats overtop of web page. It was built using the jQuery library.
This plugin inserts the necessary elements required to run Fancybox on your blog. It also groups 
images within posts using rel attributes. (Based on the code found on <a href="https://wordpress.org/support/topic/automatic-adding-lightbox-rel-and-group-to-images-in-posts" rel="ugc">this</a> 
forum thread)
To disable Fancybox per post: Add a custom field called ‘nofancybox’ and set it’s value to ‘true’. 
Instructions on how to add custom fields to posts can be found at <a href="https://codex.wordpress.org/Custom_Fields" rel="nofollow ugc">this</a> 
codex article.

WordPress prettyPhoto is a jQuery lightbox clone. Not only does it support images, it also support for videos, flash, YouTube, iframes and ajax. It’s a full blown media lightbox.
It is very easy to setup, yet very flexible if you want to customize it a bit. Plus the script is compatible in every major browser, even IE6. 
For a installation guide checkout the Installation tab above.
Usage Guide: It’s very easy to implement. Just use a rel=”prettyPhoto” attribute with the link tags you want to pop up and that’s all. You’re ready to rock.
Example: <code><a href="images.jpg" rel="prettyPhoto" title="This is the description"><img src="thumbnail.jpg" width="60" height="60" alt="This is the title" /></a></code> 
A set of short codes to use with visual editor of post/page is being cooked.
Make sure that your theme is WordPress header and footer tag enabled otherwise this plugin won’t work.
