This plugin is meant primarily for theme developers.
This plugin allows to collect photos from the the Media Manager and arrange them into albums. 
These albums can be combined into galleries. 
Both albums and galleries can be added to a theme’s navigation menu.
Note that this plugin does not provide any CSS formatting and JavaScript for frontend presentation of galleries and albums. You have to format them yourself and integrate necessary JavaScript libraries, e.g Lightbox, yourself. This plugin merely gives a framework for gallery and album creation via custom post types and registration of designs for a frontend presentation.
If you found a bug or have any questions, complains or suggestions please feel free to contact me.
Theme Integration
You have to write post type template files for your theme in order for an album or gallery to work. 
This gives Theme developers the most control over a frontend presentation and users a convenient way to create galleries through the WordPress dashboard. 
If you install this plugin, create albums and galleries and include them into your theme’s menu, you will be disappointed, since nothing will happen.
<ol>
<li>Create two php files inside your theme’s directory: <code>single-photogallery.php</code> and <code>single-photoalbum.php</code>.
<ul>
<li><code>single-photogallery.php</code> gets called everytime a gallery is about to be viewed</li>
<li><code>single-photoalbum.php</code> gets called everytime a album is about to be viewed</li>
</ul>
</li>
<li>Now you have two options.
<ul>
<li>You can register a custom design inside your theme’s <code>function.php</code> via e.g <code>$kt_Photogallery->register_gallery_design()</code> and call <code>$kt_Photogallery->render()</code> at an appropriated place inside your <code>single-photogallery.php</code> to render it depending on the user’s choice.</li>
<li>You fetch albums, images and thumbnail details, and render consistent HTML for all albums and galleries.</li>
</ul>
</li>
<li>Refere to the PHP API section for further details on how to retrieve album IDs, image IDs and thumbnail details.</li>
</ol>
Example
A basic example for a custom gallery design
<pre><code># functions.php

$kt_Photogallery->register_gallery_design ('my_gallery_design', array(
 'label' => __('My Gallery Design', 'my-textdomain'),
 'icon' => 'dashicons-format-gallery',
 'title' => __('This is my custom gallery design', 'my-textdomain'),
 'render' => 'render_my_gallery_design'
));

$kt_Photogallery->register_album_design ('my_album_design', array(
 'label' => __('My Album Design', 'my-textdomain'),
 'icon' => 'dashicons-format-image',
 'title' => __('This is my custom album design', 'my-textdomain'),
 'render' => 'render_my_album_design'
));

function render_my_gallery_design ($post) {
 global $kt_Photogallery;
 $album_IDs = $kt_Photogallery->get_albums($post);
 if ($album_IDs) {
 foreach ($album_IDs as $album_ID) {
 $album_thumbnail = $kt_Photogallery->get_thumbnail_src($album_ID);
 echo '<a href="' . get_permalink($album_ID) . '">';
 if ($album_thumbnail) {
 echo '<img src="' . $album_thumbnail[0] . '" alt />';
 }
 echo '</a>';
 }
 } else {
 printf(__('The gallery %s does not contain any albums', 'my-textdomain'), esc_html($post->post_title));
 }
}

function render_my_album_design ($post) {
 global $kt_Photogallery;
 $image_IDs = $kt_Photogallery->get_images($post);
 if ($image_IDs) {
 foreach ($image_IDs as $image_ID) {
 $image = get_post($image_ID);
 if ($image) {
 $image_src = wp_get_attachment_image_src($image_ID, 'medium');
 if (!$image_src) {
 $image_src = wp_get_attachment_image_src($image_ID, 'full');
 }
 echo '<img src="' . $image_src[0] . '" alt />';
 }
 }
 } else {
 printf(__('The album %s does not contain any images', 'my-textdomain'), esc_html($post->post_title));
 }
}

Basic integration into <a href="https://wordpress.org/themes/twentyfifteen" rel="ugc">Twenty Fifteen</a>:

PHP API
I have included a number of functions for fetching album, image and thumbnail IDs associated with a gallery or album. 
Please note that all methods starting with an underscore are considered internal and are not documented here. Although some are publicly accessible you should not use them directly unless you know what you are doing.
You do not have to create a new kt_Photogallery instance, there is already one in the global namespace.
