This module (originally created by DriesK) is an alternative way of displaying your photo albums using Flash, inside a Drupal environment.
Flash gallery module depends on image module and image gallery module. It takes existing images and galleries, prepares a custom xml-feed from them, and injects the feed into an embedded Flash file. This module is based on Simpleviewer, a free (but, alas, not open-source) customizable Flash image viewing application written by Felix Turner from Airtight Interactive.
Flash Gallery is not compatible with Image module 5.x-1.3+.
