You may have requests from your agent to turn off access to the property websites and media. Also you may need to turn off access to media for a payment problem from your client.

To make the media not accessible on the Property Website Editor click the "Demote From Delivered" button:

Note: when you try to visit the links they will still work as the system recognizes you as an admin and allows you access. However when your client visits the links will not work.
