How can you get permission from the copyright owner?
Be sure to give yourself enough time to obtain permission. There is no required timeframe in which the owner or creator need to reply by. If you do not receive a reply, it doesn't mean you have received permission.
Oral permission granted over the phone is legally valid. Good practice requires that you document permission with a letter the grantor signs and returns to you.
