In iOS 7 there is heavy usage of contacts photos in the Contacts app. Especially the Favorites tab. I refuse to sync my entire iOS with Facebook because I've seen it mess up so many people contacts and I don't want to give all my contacts info to facebook either. So how do I sync ONLY the contacts photos? And preferably 1-way, where I just keep them from Facebook without sending Facebook anything? Can iOS do this? Can any app do this (even paid)? Can I do it on the Mac?
