Can you please give me a more detailed description by what you mean by the link doesn't work?

Do you mean that when you click on the email link on the main Photo Gallery page that the email address does not appear in your email programme?

Or is that the email is being returned to you? If that is the case the server that sends the email probably has a limit on the size of an attachment with each email. If you are sending more than one photos please make sure that you send each individual photo in a separate email. If some of your photos are very large then reduce the size before you send them.
