<p><a href="http://fancybox.net/" rel="nofollow ugc">Fancybox</a> is a tool for displaying images, html content and multi-media<br />
in a Mac-style “lightbox” that floats overtop of web page. It was built using the jQuery library.</p>
<p>This plugin inserts the necessary elements required to run Fancybox on your blog. It also groups<br />
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><br />
forum thread)</p>
<p>To disable Fancybox per post: Add a custom field called ‘nofancybox’ and set it’s value to ‘true’.<br />
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><br />

Fancyboxify

This simple plugin enables Fancybox on image links. It groups all images within a single post and can also be disabled per post.

<p>RPS Image Gallery enhances the core WordPress gallery function by dynamically adjusting the column count based on viewport width and enabling an image in the gallery to either invoke a slideshow or link to another page, post or any URL. The link and link target are specified in the image’s Edit Media screen using the Gallery Link URL and Gallery Link Target fields. When an image having a Gallery Link URL is clicked, the user will be directed to that location. Images linking elsewhere are automatically excluded from the slideshow – clicking the image will not invoke the slideshow but will call the specified Gallery Link URL.</p>
<p>In addition, RPS Image Gallery combines attachments from multiple posts or pages into a single gallery, enables the use of paging – useful for galleries with a large number of images, and provides the ability to link a gallery image to the post to which it is attached.</p>
