PiwigoModx is a MODx addon that displays images from a Piwigo gallery. Manage your images inside the Piwigo manager and display these inside your site MODx front-end. This component allows you to easily retrieve and display categories, tags, images and image metadata. There are options to filter images by category, tag, aspect ratio, date of creation and more.
Because PiwigoModx is using Piwigo API (named webservices), its even possible to install MODx and Piwigo on completely distinct websites.
