How to override 'views-slideshow-pager-fields.tpl.php'? I'm taking over one of my co-workers project (i'm new to Drupal...).

I was able to override other view templates such as 'views-view--[my content type].tpl.php', 'views-view-fields--[my content type.tpl.php', but I wasn't able to override 'views-slideshow-pager-fields.tpl.php'.

What naming convention should I use to override the file?
Views Slideshow is a separate module.  This video from MustardseedMedia addresses theming for the module. I have not watched it yet, let us know if it addresses your needs.
