I was looking for a simple extension to display photos from flickr. After nosing around, I chose Art Image Viewer as it seemed to fit my need the best. Upon download, I was pretty frustrated. Nothing was working well. I thought I had wasted $20. As a last ditch effort, I fired off an email to the folks of artetics (the makers of the extension) and within MINUTES they replied! After a few volleys of communication through email, the problem was fixed! They even went into the html coding of my site to sort out the problem! This was very impressive. I can't recommend them highly enough for their excellent service! Kudos to you, Artetics! Thank you!
