Multibox Headers


DISCONTINUED Please note this plugin is no longer maintained, and you should only use if you have examined its code. Newer versions of WordPress use much better ways of including JavaScript.

Multibox Headers adds the necessary includes (JavaScript and CSS) to your WordPress pages/posts to use Multibox, from Phatfusion

Unlike other plugins, this plugin does NOT alter your content, or tweak your galleries, it merely includes the Multibox client components in the header, and leaves it up to the author, or other plugins, to make use of Multibox. One such example plugin might be WordPress Multibox PlugIn from Manfred Rutschmann.


  • Version 1.00 – Initial release.


This plugin uses the GPLv3 license. It bundles the Multibox library which uses an Open Source MIT license.


  • A snip of generated code


There are 2 ways of installation. If your setup supports it, you can search for the plugin, by name, within your WordPress control panel and install it from there.
Alternatively, you download the .zip file, unzip it, and copy the resultant multibox-headers folder to the wp-content/plugins/ folder of your WordPress instaltion folder.


Why don’t my galleries use Multibox when I click on the images?

This plugin only adds the required headers (both JavaScript and CSS) for Multibox, it does not enable content to use Multibox directly. You’ll have to use an other plugin for that, or manually edit your content as per the Multibox instructions.
