Brief
We have added some extra code to files 'previews.html' and 'previews_functions.php' for version 3.6.
 
Description
Previews images for products were not always displayed (depending on the files you were using) if using an option 'Use player for preview'.
 
Solution
We would recommend you to download an updated version of the files from here:
http://www.viart.com/downloads/previews_images-3.6.zip
 
Further, extract the above mentioned files into the 'includes' folder (in the Binary mode) and to the 'templates/user' folder of your shop. Do not forget to make a backup copy of the current files in case something goes wrong.
