There are a lot of fine Lightboxes on the market, both free and commercials, but they all need to be installed into You Confluence, in on of 2 ways:
All of the stuff below is quite generic and samples only
Filesystem based
In this case, the light box is placed in the filesystem, either under the Confluence installation, or somewhere else and linked in.
Under Confluence
Download the lightbox zip, upload it to the server and place the files under the install:
cd /opt/confluence/confluence mkdir mylightbox cd mylightbox mv ~/mylightbox.zip . unzip mylightbox.zip
Now these can be referenced as /opt/confluence/confluence id the server root, so in Custom HTML add:
<!-- MyLignbox --> <link rel="stylesheet" href="/mylightbox/css/mylightbox.css" type="text/css" media="screen" charset="utf-8" /> <script src="/mylightbox/js/jquery.mylightbox.js" type="text/javascript" charset="utf-8"></script>
Some lighboxes requires to be initiated ($ is AJS.$ for Confluence):
<script type="text/javascript" charset="utf-8"> AJS.$(document).ready(function(){ AjS.$("a[rel^='mylightbox']").mylightbox(); }); </script>
Somewhere else
Confluence page based
