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>
