Had an issue with the layout of the tiny images in the gallery, since they normally show up in a horizontal row above the small image, which was not perfect for my needs... sent an email to support and got a reply after just a few minutes.
They were very helpful and solved my problems in a short amount of time.
A good extension, a fast replying support who fixes an issue fast as well... this is something very rare nowadays.
Both thumbs up for ArtZoomIn and the Artetics team!!!
