dfGallery 2.0 is one of the coolest Free Flash Galleries. v1 with 200,000+ downloads was the hottest topic on our site and we hope to see a lot with this too. This is just the alpha release and we expect lots of feedback to get this to its best possible..
The reason for this gallery to be cool is not just its UI but the way it is built and architected. We have an amazing theme engine built to support custom themes with multiple skins for each. The administration console built on CodeIginter lets you manage multiple galleries and albums of different types.
