This latest version if brilliant. I use the Gallery, Video and Article modules on a client project and they are so easy to use. We have written our own modules that access the Cross table structure as they are so well written it was very easy to do. The support is great and they are always willing to take on new ideas and enhancements. This really is a must buy product if you are looking for a very very flexible, well written photo gallery, plus we use the Flickr part so my client just uses Flickr and photos appear on the website, even better is that all the photos are hosted on Flickrs CDN so we dont have to hold the images locally. If I could give this 100 stars I would.
We're using the Silverlight Photo Gallery 5.5 by now and it's working great. We use this module a lot for sites of customers. The looks are great and the usability is even better! Also there are many settings to customize it to your needs. Lots of options.
