Very easy module to install and use. Support is EXCELLENT. I really hope developer will keep working on this module as it gives a very nice presentation to photos. Would be nice to have back end configuration and ability to create more folders. And even if licence per domain I would be glad to pay.
I have purchased commercial version and for the amount of money they request it is worth every single penny. I will keep an eye on development on this extension. I use a lot of galleries on my clients sites so this one definitelly would be useful. Nice job!
