If you’ve got a Facebook account, you can import all your contacts from there as well. To do that, you’ll need to link your NOOK Tablet to your Facebook account. For details, see Linking Your NOOK Tablet to Facebook.
When you import your Facebook contacts, their pictures automatically show up in the Contacts app. As with when you import contacts from Google, the only information imported into your NOOK Contacts app is the name and email address of the person.
