Piwigo
Piwigo is photo gallery software for the web, built by an active community of users and developers. Freely available extensions make Piwigo easily customizable. It is notable as a system with many features. Piwigo is a web-based system that is free and open-source, in contrast to Flickr or Picasa. It is licensed under the GPL. It is written in PHP and requires a MySQL database. It can be installed on your own server. Deployment. Piwigo can be deployed using various methods in a hosting environment. Users download the current version of Piwigo from Piwigo.org. Either they download  the full archive and upload the source code to their hosting environment or they download the NetInstall (a single PHP file), upload it to their hosting environment and let it download the full archive automatically. Many shared web hosting services also offer automated Piwigo installation through their control panel: for example, Piwigo is available in SimpleScripts and Softaculous. History. Piwigo (originally named PhpWebGallery) was written by Pierrick Le Gall as a personal project in 2001. Inspired by the opensource web forum phpBB that he installed for his university website, he chose the GNU General Public License to distribute Piwigo and  start a community around the project. The first version of Piwigo was released in April 2002. In 2002, Piwigo became multilingual. In 2004, a bugtracker was installed in order to enable co-operative working as a team. In 2005 an online extension manager made contributions easier to share. In 2006, themes made customization possible. In 2007 plugins were introduced to extend Piwigo features. In 2009 PhpWebGallery was renamed Piwigo and pLoader (Piwigo Uploader) made photo uploading easier for Windows, Mac and Linux users. In 2010, digiKam, Shotwell, Lightroom made it possible to upload photos to any Piwigo gallery, an enhanced  web uploader was provided in Piwigo 2.1 and Piwigo.com was launched (dedicated hosting for Piwigo). As of 2013, there were 10 members in the Piwigo team, 100 translators, a website available in 12 languages and a thriving community. In June 2014 version 2.6.3 has been released.
