First we're wondering if this addon works on Joomla 3.6.x and Virtuemart 3.0.16.

Secondly we wonder if it is possible to display it differently, we want to be able to upload both an image for the pdf and the actual pdf and show it in rows and columns under description.
Basically it would just link the pdf to the image which is shown to the customers.
Is this possible?

Or can it take an image of the first page of the pdf automatically and link to that?

Thanks in advance!
