Interface of Piwigo
|Developer(s)||Pierrick Le Gall, Piwigo Team|
|Stable release||2.0.8 / 26 January 2010|
PhpWebGallery was originally written by Pierrick Le Gall as a personal project, unaware that other projects like it existed. On April 15, 2002, the first version of PhpWebGallery was released 
In order to allow non-programmers to use PhpWebGallery, the software was restructured, this time utilizing templates. This allowed users to change the look of the gallery with only HTML and CSS.
Later versions allowed for images to be stored in any arbitrary location as well as any arbitrary category. The latter was eventually dubbed a "virtual category").
Creator Pierrick Le Gall announced the pending name change from PhpWebGallery to Piwigo on his personal website on September 24, 2008. The stated reasons for the change in name were:
- shorter : easier to remind
- unique : a search engine request on "Piwigo" will bring you to the Piwigo project pages
- no PHP in the name : I now find it odd to make the technology obvious in the application name
- keeps the PWG letters
Today, Piwigo is supported by 14 developers and a thriving community.
- Virtual categories
- Each image is bound to one or more virtual categories. By associating images to multiple virtual categories, albums can be displayed in multiple, arbitrary groupings depending on the target audience.
- The appearance of the photo album is defined from a template. There are various templates provided by the development community.
- Users are able to navigate using five different modes: category, date (using a calendar), recent images, and tags.
- Access control
- Access control is handled by the user manager, restricting and granting varying levels of access to images and albums.
- Plugins expand capabilities of PhpWebGallery. Plugins exist that integrate Google Video, Dailymotion, YouTube, Google Maps, Google Earth, as well as implementing a Sitemap.
Other features are listed on the project's homepage.
