Just to clarify this topic;
Image displaying has been changed on VM3.0.12. With this new version, it is now possible to have different thumbnail sizes (i.e: 300x300 thumbs on category page, 100x100 thumbs on product details page for the same product)
This requires some coding modification on our template as well, because the VM core function of
displayMediaThumb() (which we are using to display the pictures on CleanMart template) has been changed.
The new update of CleanMart will cover this patch. No worries.
