Free PHP Scripts by Gscripts.net

This module enables automatically importing directories as galleries of images on a per-date basis. For each gallery, a photobar preview of the gallery is created for display on the main-page. Where this module shines is it's simplicity and automation. Photos need simply to be placed in the required directory on the server, and the photobars will automatically be created and inserted in the correct place in the site. Unlike other photo managing modules, no installation is required nor does it require altering Drupal's database.
