If you're a Flickr user you probably know it can get tricky sharing photos with non-Flickr members if you want to keep your photos set on "private." One simple way to share your pics without changing the privacy levels on your account and albums is to use Invitr. The tool allows you to specify one (or more) private pictures, which you then share with whoever you want by sending them an e-mail. This allows you to extend the usual Flickr statuses (such as private, public, friends and family).
How does it work? You log on to your Flickr account, select the photos you want to share and fill out the email address field. Set the expiry date and the person you specified will receive an email with a unique link to view the selected photos.
