Template Files

Normally, in printing fields in Drupal 7 for the usual nodes, we use:

<?php print render($content['field_phone']); ?>

Now, we have a rather similar but different format for Drupal Commerce products display. You may use below "Commerce" equivalent of what is normally done for the usual Drupal nodes. This is assuming you want a field item within your product nodes printed or displayed on your template or TPL file:

Option 1: Field Slideshow and Field Collection modules

Provides a Slideshow formatter for Image fields, using JQuery Cycle plugin.Compared to Views slideshows, building the slideshow from multiple nodes, this module builds it from a single node, with a multi-valued Image/Media/Field Collection field.
