Permissions and releases
Q. I keep e-mailing the Right People for permission to reproduce an article or an image without success. They never reply. Any suggestions?
A. After your third polite e-mail has been ignored, try language like this:
"Dear So and So,
I've e-mailed you several times regarding permissions but have received no reply. Unless you answer this e-mail I will consider your silence as permission to reproduce the material since you have raised no objection."
That should get you a response but if not I would use the information or graphics as you wanted to, providing all proper credits to the copyright holders. Link to their site if they have one or if you can. Keep a record of your e-mails to show good faith. Then let them contact you if they want the file or picture pulled.
