Gallery 3.0, the latest version of the widely used open source photo gallery manager, has finally been released a year and a half after active development on the project started. A large number of modules are already available for Gallery 3 over at GalleryModules.com.
I already installed Gallery 3 on my server here and imported all the photos and data from my Gallery 2 installation. Importing everything went seamless. Gallery 3 is quite a bit different from its earlier iterations, however, and I’m still trying to sort through how to replicate some of the features that I had in the old installation (Gallery 3 eliminated some features from the core in order to emphasize speed and the ability to handle large sets of photographs, though many of the removed features can easily be added with add-on modules).
