This plugin allows you to create special links that check whether a user is logged in and then follow the link if they are or show an ajax-powered login form in a simple lightbox if they are not. Once the user fills out the login form with valid credentials they will be logged in and redirected to the page the link points to.
<h4>Scenario</h4>
Let’s say you’ve got a page on your site that only logged in users are able to access. It could be a private page or ideally it is a page that is set up to show a standard login form to users who are not logged in. With this plugin you could add the class ‘ajax-login-trigger’ to all the links that point to that page, then when a user clicks one of these links an ajax request is sent to the server to check whether the user is already logged in, and if they are the user is redirected to the page without ever noticing that the login check was done, or if they aren’t logged in they’ll see a login form appear in a simple lightbox. When the user fills out the form, a second ajax request is sent to the server to attempt to log them in, and if successful the user is redirected to the page.
<h4>Customize It!</h4>
This plugin includes lots of hooks and filters that allow for all sorts of customizations and unique use cases. Here’s a quick list:
Actions:
<pre><code>mm_ajax_login_before_form_outside
mm_ajax_login_before_form_inside
mm_ajax_login_extra_buttons
mm_ajax_login_after_form_inside
mm_ajax_login_after_form_outside
</code></pre>
Filters:
<pre><code>mm_ajax_login_trigger_selector
mm_ajax_login_form_title
mm_ajax_login_status_message
mm_ajax_login_username_label
mm_ajax_login_password_label
mm_ajax_login_rememberme_text
mm_ajax_login_lost_password_text
mm_ajax_login_button_text
mm_ajax_login_custom_login_action
mm_ajax_login_email_login_fail_message
mm_ajax_login_success_message
mm_ajax_login_fail_message
mm_ajax_login_allow_email_login
</code></pre>
Many things are possible with these hooks. The hooks <code>mm_ajax_login_before_form_inside</code> and <code>mm_ajax_login_after_form_inside</code> allow you to add any custom input elements to the form. When the login form is submitted all of the values from the input elements included in the form will get passed to the PHP function that processes the ajax request, which will then pass the data to the <code>mm_ajax_login_custom_login_action</code> filter. You can intercept the incoming data using this filter and proceed with any custom action you want, like registering new users and logging them in during the same action.
<h4>Filter Examples</h4>
Use a custom selector for the trigger link:
<pre><code>add_filter( 'mm_ajax_login_trigger_selector', 'prefix_custom_login_trigger' );
function prefix_custom_login_trigger( $selector ) {

 // Custom selector goes here.
 $selector = '.my-custom-selector';

 return $selector;
}
</code></pre>
Use a custom status message:
<pre><code>add_filter( 'mm_ajax_login_status_message', 'prefix_custom_status_message' );
function prefix_custom_status_message( $status_message ) {

 // Custom status message goes here.
 $status_message = 'Magic happening...';

 return $status_message;
}
</code></pre>

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.

when the lightbox pops up.

aperture, focal length, shutter speed, and created timestamp.
[gallery meta=”true”]
<ul>
<li>class</li>
</ul>

Lightbox Gallery

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

It is beyond any definition of bad
