the main page edits

Dear Sir,

Thank you for creating such a great Gallery! We are using a gallery 2.3 and having a problem with link. Could you let me know how to link "email address" on the description of the main page?

Here's the link for our website gallery page as the following:

http://hearnestorybook.com/photos/main.php

Which file or code should we change?

Best,
