Yes, i understood the problem, please visit our DEMO where the "flxible_FlypageV2" is used and there are some couple pictures are added:
www.flexiblewebdesign.com/virtuemart-theme/index.php?option=com_virtuemart&Itemid=58
Click to any other picture rather than principle image, and then click the "magnify" icon, you will see that it enlarges the parent picture only. Which means, this is not a bug that it behaves like that in your website. This is actually how our VM theme was developed.
This would have been achieved with a little jQuery path actually (basically clicking the thumbnail would update the lightbox's destination URL to that new thumbnail's parent picture) but since VM1.1.xx theme has become old-fashion, (we are more focusing on our VM2 templates), we have stopped updating the VM1.1.xx theme.
If you think this will create confusion to your visitors, you can simply hide this magnify icon with this CSS rule below:
.clickzoom {
display:none;
}
(you can add this CSS rule to any CSS file that is loaded in your website)
