This is a contributed Drupal module built for Drupal 7 and Drupal 8. It is a comprehensive photo album module for managing multiple photo galleries. The Drupal 8 version is geared towards professional photographers with enhanced security and privacy settings. Locked galleries, password protected galleries, even galleries that can be collaborated on with multiple users. Send your clients an email with the gallery password and invite them to view the beautiful photos that you took for them while keeping the images private from the rest of the world.
Other contributed modules can be used to build a productive site where clients can flag their favorite photos for you to review and enhance as needed. Even purchase and download the photos directly from your website.
