Microsoft Outlook lets you associate photos with the contacts in your address book. Most Facebook users have profile photos associated with their accounts. Wouldn't it be great if you could download those profile photos into Outlook? That's the idea behind OutSync, a free utility that copies photos of your Facebook friends into matching contacts in Outlook.
Just install and run the program, then give it permission to access your Facebook account. (I can understand being a little skittish about security, but the developer of OutSync works for Microsoft, so you're probably safe. That said, this is not an official Microsoft product.)
In a minute or two, OutSync should find Facebook friends that match entries in your address book. By default, it will select all of them for syncing, but you can manually remove any contacts you want by clearing their accompanying checkbox.
From there, just click Sync and you're done! In my quick, informal test, OutSync worked exactly as advertised, pulling a few dozen photos from Facebook into Outlook.
