OutSync is a free software to sync photos of Facebook friends with Outlook contacts. If you have some contacts that are in both Facebook and Outlook, it will download their Facebook photos, and will add them to your contact list of Outlook.
OutSync is quite simple to use. You need to install it on your Windows PC (on which you have Outlook installed). After that, it will check all your Outlook contacts, and will see if they exist in Facebook as well. It will show all Outlook contacts that it was able to find in Facebook, and their Facebook photos. You can choose to sync the photos of all the Facebook contacts that it was able to match, or selectively sync just a few.
