DISCONTINUATION NOTICE: Development on this plugin has ceased in favor of the carousel module in the <a href="https://wordpress.org/extend/plugins/jetpack/" rel="ugc">Jetpack plugin</a>. I recommend you use that plugin instead — it’s much more full featured.
Makes the native WordPress galleries use a lightbox script called <a href="http://colorpowered.com/colorbox/" rel="nofollow ugc">ColorBox</a> to display the fullsize images right there in the page. No modifications required.
You can also make single non-<code>[gallery]</code> images use the lightbox by giving their links a class of “lightbox”, like so:
<pre><code><a href="..." class="lightbox"><img src="..." alt="..." /></a>
</code></pre>

This minimal WordPress lightbox plugin adds high performance, responsive jQuery lightbox functionality to your images. When standard WordPress images/galleries are clicked, the background fades out into black as images display in lightbox popup. Galleries can be navigated with on-screen arrows, touchscreen swipes, or pressing arrows keys.
In order for WordPress images and galleries to be lightboxed: 
– You must select the “Media File” option when choosing where thumbnails should link. You can also select the “Custom Link” option if it links directly to an image file. This should work for any image file, even if it’s hosted on another website. 
– Enable on each post by checking “Enable lightbox” on the WP Featherlight settings. 
– You can also lightbox videos, iframes, and ajax content by adding data attributes to your content. For more details on custom content loading, check out the <a href="https://github.com/noelboss/featherlight/#usage" rel="nofollow ugc">featherlight documentation</a>.
My plugin is simply a forked version of the original <a href="https://wordpress.org/support/plugin/wp-featherlight" rel="ugc">WP Featherlight plugin</a>. Only difference is the original loads the featherlight CSS/JS on every page whereas mine only loads when you manually enable. Big thanks to Yin and Walter for contributing.
<h4>Features:</h4>
<ul>
<li>Ultra-lightweight – even more lightweight than the original WP Featherlight since the lightbox CSS/JS is not loaded automatically.</li>
<li>Manual activation – to enable lightbox functionality, simply click the checkbox in your post settings.</li>
<li>Retains WP Featherlight features – has all the same features and filters as the original WP Featherlight plugin (up to version 1.3.3)</li>
<li>Supports WEBP image format.</li>
</ul>
