| From your computer, select your photos and transfer them to your gallery with pLoader, the remote client for Piwigo. You can also perform massive FTP upload and then use the synchronize function in the gallery administration. Piwigo can aggregate photos coming from several servers in a completely transparent way for end users. Dispatch photos in your category tree. There is no limit on the tree depth and a photo can belong to several categories. Virtual categories let you organize your gallery structure without worrying about the directories layout. At any level, visitors can flatten the structure and see all the photos under the current category level. And you can set permissions on each category to fine tune your gallery for each user. Tags offer another way to browse your photos. Start from the tag cloud and refine the photos set with multiple related tags or choose a tag from a photo and enlarge your vision. For example with the "Paris" tag, 183 photos are available and if you add the "night" tag you will reduce the set to 45 photos. If you add the "Sylvia" tag it will remain only 5 photos with Sylvia smiling in Paris streets by night. Browsing by tag allows you to add or remove tags to fit your desires, even if they change by the time passing. Keep track of time, use the chronology. Cameras know when a photo was taken and store this in the picture's metadata (EXIF). Piwigo remembers this date and gets the best from this information : browse your photos for a day-to-day trip, a month-to-month one and display your photos' calendar. Explore the best rated photos and the most seen. Rediscover forgotten photos with the random set feature. Piwigo provides a multiple criteria search engine to help you. Visitors can also turn on the slideshow on any photo set. Everybody can read the comments from a dedicated, filter-capable page. Add users yourself or let them register, grant them permissions on photos and categories to filter your audience. Your users can get notified of news by email or by RSS feed. You would create groups to make permission management simpler. Several user levels are available : visitor, generic, member, administrator, webmaster. Get feedback from your visitors: turn on user comments and rating on your gallery and don't care about SPAM, we use advanced techniques to filter them. Piwigo reads photo metadata such as EXIF and IPTC. Photo metadata can be synchronized into the database. For example, you can use IPTC to fill the photo description and photo author. EXIF metadata stores camera settings and Piwigo can display any of the photo technical settings (aperture, shutter speed, ISO, etc). Piwigo can produce pretty URLs with tag/category/photo names included, which is quite nice for search engines because it makes the URLs meaningful and increase your pagerank. Administrators benefit from nice visits history statistics, from year to hour precision. Visits history can also be filtered, so you can follow visits on a specific photo, only the high resolution downloads or only visits between 2 specific dates. Piwigo comes with localization features. To make it simple, it means that you can turn your website into several languages, including by default : English, Español, Deutsch, Français, Italiano, Nederlands. Other languages will come as extensions and may be integrated in standard release. Presentation customization is possible thanks to themes and templates. Colors and icons changes are made with themes. Deeper changes like page layout are possible with templates. No need to understand the PHP core coding, templates are nearly HTML and themes are mainly CSS stylesheets. Share your templates and themes in the extension manager, and make the community grow. A web API is available so that you can perform requests and administration from other applications. For example, you can add categories or fetch a search result in another PHP tool like a blog or a forum. |
