Shutterbook - Drag-n-Drop Photo Sharing is running an open beta right now where they are giving out free premium lifetime accounts. This is a service a lot like Flickr. The plus on Shutterbook is that it is an easy drag-n-drop to upload your photos. Of course OS X users could always use the iPhoto plugin for Flickr that will allow to import your photos at the touch of a button. The Shutterbook premium account does have a limit of 20,000 photos, compared to the Flickr premium account that is unlimited. Still being a free beta its worth a look.
