Hi,
Normally the "Additional Pictures Slider" should be triggered when there are more than 3 additional picture. Did you disable it on purpose?
I wonder what your backends settings are..
1- Navigate to the Joomla Backend
2- Open this plugin:
Flexible VM3 Template.
3- Click the
Zoom Effect tab from top
4- Scroll down little bit and find this section:
Additional Pictures Slider Settings
Tell me what settings you have for the add. picture slider section.
You should have these (by default, unless you change them):

If you already have these settings, then something must be wrong with your website (probably a jQuery Conflict) that prevents additional picture slider to be triggered. Provide me the URL where you got this screenshot and let me check the page against JavaScript error.
Regards.
