link to triger the plugin

The javascript method we use to invoke the lightbox is show_facebox();

So if you want to only enable it on a button click you must add the
onclick=”show_facebox();” attribute on that link. Also, if you don’t want to popup automatically, remove any reference to that function in scs/launch.js

hey mate, please excuse my noobness but where would i add this onclick=”show_facebox();” attribute? little confused about removing those references from the launch.js ?? guessing there is no https://www.website.com/facebookappcall.xx that i can use to launch the plugin?

You need to switch to html view and add the following code:

<a href="#" onclick="show_facebox();">link text</a>

Please note that the show once every x days option is taken into account. So you may need to set it to 0 and have a very high delay
