The Flickr API plugin provides tools for displaying your flickr galleries, sets, photostream or favourites and more using a shortcode in posts and pages or as a widget. You can choose the size of image you want, whether it should be linked to another image size or back to flickr or not linked at all, how many images to show and more…
There are some built in options for displaying your images as a simple slideshow or using the Galleria jquery plugin. Alternatively you can choose to style the output yourself and use your own javascript.
For developers the plugin also gives you an easy method for calling and caching API responses both in PHP and javascript, and lots of useful tools for working with those responses.
<h4>Usage</h4>
You will need to get an API key from flickr to use this plugin. Under the ‘You’ menu look for ‘Your Apps’. Click to get a key and then go to the media settings screen to add your API key and user name. The plugin will automatically determine your NSID so you never need to look this up.
To use the plugin either generate a shortcode using the media upload/insert button and selecting what you want to get or use the Flickr widget provided.
<h4>For developers</h4>
The plugin exposes its methods for your use in themes as template tags but the main one you may find useful is <code>flickr_api()</code>. This is a general function for calling any API method with the parameters you specify.
<pre><code><?php
$response = json_decode( flickr_api( $method, $params, $cache ) );
?>
</code></pre>
All responses are in JSON format so you will need to use <code>json_decode()</code> to use the response in PHP.
<pre><code>@param $method: (string) This is the API method to call
@param $params: (array) Additional arguments to pass into the call such as user_id, photoset_id, gallery_id, text, tags etc...
@param $cache : (bool) Whether or not to cache the response based on the arguments passed in
</code></pre>
You can use the API via javascript as well:
<pre><code><script>
var photos = flickr_api( method, params, cache );
</script>
</code></pre>
NSID lookup:
<pre><code><?php
$nsid = flickr_get_user_nsid( $username );
?>
</code></pre>
Just pass in the Flickr username of the person to get the NSID for.
<h4>Filters/Hooks</h4>
flickr_galleria_themes
You can enable the choice of custom or purchased galleria themes by extending the themes array. Useful if you want your theme to have a choice of galleria theme beyond the ‘classic’ style.
<pre><code><?php
add_filter( 'flickr_galleria_themes', 'my_galleria_themes' );
function my_galleria_themes( $themes ) {
 $themes[ /* full or relative url to theme js file */ ] = __( 'Theme Name' );
 return $themes;
}
?>
</code></pre>

Flickr API

A comprehensive Flickr plugin that makes it easy to show off your images in style.

Importance: 
From 0.7.1, the default view changed to Colorbox due to the license regulation by the plugin directory. If you would prefer the prior Lightbox to Colorbox, you need to get the script from the setting page.
The Lightbox Gallery plugin changes the view of galleries to the lightbox.
<ul>
<li>Lightbox display of Gallery</li>
<li>Tooltip view of caption of images </li>
<li>Displays the associated metadata with images</li>
<li>Divides Gallery into several pages</li>
<li>Extends the default Gallery options</li>
<li>Additional settings are set in the option page</li>
<li>Switch to the Highslide JS display</li>
</ul>
You can also make regular images appear in a lightbox. See Faq.

<h3>How to use</h3>
How to use this plugin is basically the same as the way to add [gallery] which has been adopted 
by over WordPress 2.5. Lightbox Gallery plugin automatically converted the default view of gallery 
into the lightbox view. Photo captions are displayed as tooltips. Photo descriptions are displayed 
when the lightbox pops up.
<h3>Advanced settings</h3>
There are three additional options to extend the shorttag [gallery].
<ul>
<li>lightboxsize</li>
</ul>
The image size when the lightbox pops up. The default is medium, but you can change to full.
[gallery lightboxsize=”full”]
<ul>
<li>meta</li>
</ul>
Defines whether the exif information is displayed. The default is false. 
If you want to show the photo info, set true. The exif shown on the lightbox includes camera body, 
aperture, focal length, shutter speed, and created timestamp.
[gallery meta=”true”]
<ul>
<li>class</li>
</ul>
Adds a class attribute of the gallery. The default is <code>gallery1</code>.
[gallery class=”gallery2″]
<ul>
<li>nofollow</li>
</ul>
Adds the attribute, rel=”nofollow”. The default is false.
[gallery nofollow=”true”]
<ul>
<li>from, num</li>
</ul>
Defines from which and how many photos are displayed. 
If the number of photos is over that of <code>num</code>, the navigation will be shown. 
You can use the navigation option almost same as the <code>wp_link_pages</code> function.
[gallery from=”5″ num=”10″]
<ul>
<li>pagenavi</li>
</ul>
If you would like not to show the navigation, set <code>0</code>. The default is <code>1</code>.
[gallery num=”10″ pagenavi=”0″]
<ul>
<li>colorbox_settings</li>
</ul>
You can set the additional settings for Colorbox. See <a href="http://www.jacklmoore.com/colorbox/" rel="nofollow ugc">Colorbox official site</a>.

Lightbox Gallery

Really, nothing works as expected, looks broken and counter-intuitive. 

It is beyond any definition of bad

The Lightbox Gallery plugin changes the view of galleries to the lightbox.
