Hi,
If you have little coding experience, it is not a challenging thing to handle. You can easily get back to original VM state (lightbox for product details page)
Open this PHP file:
/templates/YOUR_TEMPLATE/html/com_virtuemart/productdetails/default.php
Find the DIV element that wraps the product pictures and additional product pictures,
(i.e: it starts with
<div class="main-image">) and delete the whole DIV. Instead, insert this code snippet:
<?php echo $this->loadTemplate('images'); ?>
this should be the patch you are looking for.
regards.
