This plugin allows you to use Slimbox (Lightbox clon) in your post’s images, it automagically adds the required code, and it is backwards compliant as it works with rel=”lightbox” attribute, if you already had Lightbox installed. If you don’t like the code being added automatically, you can turn this off by editing one line in the plugin editor (wp-slimbox-reloaded.php). By the default, all images included in a given post will work as a gallery (rel=”lightbox[post-#]”).
Mootools 1.2 is bound to this plugin, for those who haven’t implemented it yet, but you can modify one line in the code and tell the plugin if you already have it. The variable to look for is $already_has_mootools = ‘yes’;
It also features a code quicktag in the code editor (when you write a page or a post).
Mostly I made arrangements of code in WP Lightbox 2 plugin by Safirul Alredha (http://zeo.unic.net.my/notes/lightbox2-for-wordpress/) and the original Slimbox plugin by Jorge Serra (http://code.google.com/p/slimbox-wp/) to run up the latest versions of both Slimbox (1.64 at the writing of this plugin) Mootools (1.2), and of course: WordPress (2.6).
I noticed there’s also an other Slimbox – WordPress plugin but it is outdated and the automatic attachment of code it doesn’t seem to be working, though I haven’t made extensive tests. I’m talking about the one made by Peppe Argento(http://www.4mj.it/slimbox-wordpress-plugin/).
