<p>When you upload an image, WordPress will automatically scale/crop it to many different sizes. If you’re not happy with the auto-crops, use this plugin to upload an alternative image.</p>
<p>If you have images showing up in your theme already, there’s nothing you need to do after activating this plugin. All WordPress functions that provide the thumbnail should now automatically work with your override image.</p>
<p>This plugin will add a metabox to every post type and allow you to modify every image size (built-in and custom ones added using add_image_size). You can use two filters to change these (image_override_post_types and image_override_sizes). For examples, see the documentation.</p>

<h4>Hello Theme Developers!</h4>
<p>Have you ever added a Featured Image to a post and thought to yourself, “I wish I could add more than one image this way”? Well, now you can. Featured Galleries mirrors the Featured Images functionality of WordPress. The only difference is that posts get an entire gallery rather than just a single image. These galleries behave almost exactly like Featured Images, and make use of  WordPress’s built in Media Manager. Users can select images, define the order, and save the gallery, all through a simple drag-n-drop interface.</p>
<p><strong>Note</strong>: This plugin DOES NOT HANDLE THE FRONTEND HTML CREATION. That is left for themes to handle, to allow for maximum flexibility. Featured Galleries just handles the backend/admin interface for creating featured galleries and storing them as metadata. You will need to integrate this into your theme, or use a theme with prebuilt integration.</p>
<h4>Quick Start Guide to Integrate Into Themes</h4>
<p><em>For more information, see <a href="https://github.com/Kelderic/featured-galleries/wiki" rel="nofollow ugc">GitHub Wiki</a></em>.</p>
<p>I’ve tried to make this as intuitive as possible. Themes can integrate Featured Galleries in the same way they integrate Featured Images. Inside any template file where the gallery should appear, the theme will call the <a href="https://github.com/Kelderic/featured-galleries/wiki/get_post_gallery_ids" rel="nofollow ugc"><code>get_post_gallery_ids()</code></a> function. As long as it is used inside the loop, the function doesn’t need any parameters. By default, it will return an array of image IDs.</p>
<h4>Example</h4>
<p>Set inside the Loop. This returns all images in the Featured Gallery, as an array, then loops through to display each using an HTML <code><img></code> tag.</p>
<pre><code>$galleryArray = get_post_gallery_ids(); 

foreach ( $galleryArray as $id ) {

    echo '<img src="' . wp_get_attachment_url( $id ) .'">';

}
</code></pre>
<p>You can also customize the returned value from the function to suit your needs. See the full <a href="https://github.com/Kelderic/featured-galleries/wiki/get_post_gallery_ids" rel="nofollow ugc">function documentation</a> page for details.</p>
<h4>Custom Post Types</h4>
<p>The plugin comes with a filter to easily add Featured Galleries to custom post types. See the <a href="https://github.com/Kelderic/featured-galleries/wiki/fg_post_types" rel="nofollow ugc"><code>fg_post_types</code></a> documentation page for details.</p>
<h4>Customizing the Media Manager</h4>
<p>The media manager can be customized in sevearl ways. See the <a href="https://github.com/Kelderic/featured-galleries/wiki/fg_show_sid℮bar" rel="nofollow ugc"><code>fg_show_sidebar</code></a> and <a href="https://github.com/Kelderic/featured-galleries/wiki/fg_use_legacy_selection" rel="nofollow ugc"><code>fg_use_legacy_selection</code></a> filter documentation pages for details.</p>
<h4>Want to Help?</h4>
<p>I’d love some help with internationalization. It was working at one point, but drivingralle did that code because I don’t really understand it, and I’m not sure it’s still working.</p>


Featured Galleries

So glad I've discovered this, there are so many bad sliders out there I was driven to make my own too. This plugin does all the heavy lifting for me.
