It should work. Those DIV's can be separated and can be positioned anywhere in the
/productdetails/default.php file
But, probably you made a PHP coding mistakes. There are lots of
if...end conditions. Make sure you are not destroying the
if..end conditions.
Did you get a PHP error after you attempted to take them apart?
Separate the "additional images" slider (from the main-image), by starting from this line:
<?php // Showing The Additional Images
Which won't destroy the PHP,
also don't forget to include those 2 lines to
/productdetails/default.php$plugin=JPluginHelper::getPlugin('system','flexibleZoomEffect');
$params=new JParameter($plugin->params);
which are necessary to get the parameters from Flexible Zoom Effect plugin.
