If you are looking for a cool lightbox effect plugin for WordPress, Shadowbox JS is the answer.
The best thing about it is that it supports so many media formats including video. Therefore you can make Youtube videos, for example, open in a lightbox style effect very easily by using this plugin.
This plugin can also be used as a drop in lightbox replacement, without requiring you to edit posts already using lightbox.
By default this plugin will use Shadowbox for all image links, movie links, audio links and YouTube/Google Video links including those generated by the [ gallery ] shortcode.
