Fastest way to set a contact picture on Android
Unfortunately there is no simple, fast solution to this, Facebook has actively made this difficult and even though there were solutions for older versions of Android, they all related to the Facebook API, not Android which was just doing documented calls that are not supported any longer. 

However, if your father uses Google+ you CAN sync Google+ and Google account pictures to contacts.

Open Google+ and go to Menu (3 lines) and select Settings, then tap the Google account used on the device, scroll down to Contacts, and in that menu enable "Keep contacts up to date". Note that this will also put your user account and Google account avatar in sync, and most SMS/MMS Messaging apps will use this information as well and display the contacts profile picture in the message stream.

Contacts can also be edited online by logging into the Google account in question and going to Google Contacts page. Again it is not speedy, but it will work, and there is some import/export functionality on this page as well, but I don't believe it relates to profile pictures.
