<p>This plugin was written to take care of the invalid HTML that WordPress produces when using the <code>[gallery]</code> shortcode.</p>
<p>It does a bit more than that though.  It will integrate with many Lightbox-type scripts and allow you to do much cooler things with your galleries.  Plus, it has a couple of extra options that you can play around with.</p>
<h3>Features</h3>
<ul>
<li>Uses HTML5 <code><fig></code> and <code><figcaption></code> elements.</li>
<li>Integrates with <a href="http://schema.org" rel="nofollow ugc">Schema.org microdata</a>.</li>
<li>Uses the <code>aria-describedby</code> attribute to make images + captions more accessible to users with disabilities.</li>
<li>Validates the invalid code that WordPress spits out.</li>
<li>Several options on how you want your gallery images.</li>
<li>Allows multiple galleries in a single post.</li>
<li>Ability to set the number of images shown in each gallery.</li>
<li>Ability to exclude or include any images from your gallery.</li>
<li>Doesn’t load any extra CSS or JavaScript unless you choose to do so.</li>
</ul>
<h3>Integrates with 18 different Lightbox-type scripts</h3>

Cleaner Gallery

A cleaner WordPress [gallery] that integrates with multiple Lightbox-type scripts.

DefProc

<p>WordPress plugin to automatically add rel=”lightbox” attribute to link wrapped images, as placed into WordPress posts.</p>
<p>This plugin requires lightbox or slimbox (or any lightbox-compatible image handler) to also be installed on your site, either as part of the theme, or via a plugin. If either lightbox, or add-rel-lightbox is not activated at any time, your site will revert gracefully to the standard “open image as new page”.</p>
<p>The plugin currently only works with images placed into posts using the “add media” dialogues, and will only apply to images that are in your media library. However, it will also <em>not</em> interfere with any images that have already have attributes applied to them.</p>
<p>add-rel-lightbox also works with the [gallery] shortcode, adding the rel=”lightbox” attribute to links created by it. Note that you will have to use the <code>[gallery link="file"]</code> format, or select “Image File” when inserting the gallery for lighbox to work as expected. Galleries that link to the attachment page are unaffected by this plugin.</p>
<p>In addition to applying rel=”lightbox”, this plugin will retrieve the media library caption for any images, and correctly escape any html entities, so that the caption is displayed as expected in the lightbox.</p>


add-rel-lightbox

Add rel="lightbox" to <a> wrapped image links in the content and to [gallery] image links, and include captions for lightbox/slimbox
