With the site I spoke of they had one link that stated "Ask for permission to view photos".
You select that link and it brings up a box for communications that allows them to write in a personal message to the link owner. It is then sent via email to the link owner.
The link owner receives the email and then goes to a page that has the links "Allow Access, Deny Access". They slelect the link they find more accurate and then an email reply is sent to the user that asked for permission. This will state "X Link Owner has given you permission to view X Link onwers photos" or "X Link Owner has denied you access to their photos".
Make sense?
