<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.

WP ImageViewer

Simple and nice modal plugin.
It should just work on most images that provide a modal. If an image doesn't work, let me know in the support forum.
