[Help Wordpress] Wordpress Default Gallery with custom with custom variables

Wordpress Default Gallery with custom with custom variables

Hi, great slider.

In my example, I have a royal slider default template that uses the wordpress image gallery to create a slider. It works great, and even pulls in caption, but i want to be able to pull in some custom variables as per http://help.dimsemenov.com/kb/wordpress-royalslider-advanced/wp-adding-your-custom-variables-to-slide-markup-editor

How do i take the example given below and apply it to my need which is to use a custom taxonomy and a custom field?

function post_id() {
        return $this->post->ID;
    }

Thanks, Bodhi
