You can login to your Gallery using the password that you have been given. If you have not yet received a password this means your images are not yet finished and ready for viewing.
Once you have decided what photos you want you can click Favourite on the image and enter your email address (you only have to enter your email address once). By doing this I can see what photos you have chosen. Please ensure that you advise once selection has been made.
Once given your password your Gallery will be active for 1 week for you to chose your images.
