Try right-clicking in the body of the message and select "Add sender's address to.....  Allow remote graphics list"

Automatically load pictures and rich text view for emails from specific senders ("picture white list"?), potentially activated by a right click when in the folder view. An example for when this would be attractive is mailing list emails which routinely include pictures - since these emails can be "trusted", I would like pictures to be loaded automatically when opening the email.
