I have tried a number of Joomla photo galleries and have found all of them to be lacking in features or are very complex to configure. FW Gallery strikes a perfect balance. It provides the features that my clients need, without being overly difficult to use, which is important since most of my clients chose to maintain their own sites.
The only thing I'd like to see is the ability to resize thumbnails after they have been created. Other than that, I think it is perfect for my needs.
Keep up the great work!
