The stage module taps into Drupal's revision system to allow host-based staging of content stored in the database. For content types specified in the admin section, new content or edits to content are stored as revisions, but the node itself retains its current revision until an administrator pushes the content (also in the admin section). A set of changes between pushes is grouped and pushed all at once, and the change set is named upon push. The list of revisions associated with a given change set can be viewed both before and after a push.
I-image facilitates image viewing on your Drupal site. It uses Flex to offer an easy-to-navigate tree structure for browsing your images and photo galleries with no page refresh. Images can be zoomed, rotated, and panned from within I-image.
