Symptom
Images pasted into Address Book vCards do not appear in Mail messages.
Solution
This is expected behavior. However, if you have a .Mac account, the Mail application can automatically show pictures in messages you receive from other .Mac members. Your picture also appears in messages you send to other .Mac members.
Note: The picture is retrieved from a .Mac server by Mail, it is not a message attachment.
