Facebook’s new Graph Search allows you to easily see anybody’s photos.
First, search for someone who is not a friend. Most often, if you navigate to their photos, you see something like this:
You can’t see any photos because their privacy settings are not set to ‘Public’. It’s what you’d expect.
Use Graph Search to bypass privacy
If you put Photos of <name> or Photos by <name> into the new Facebook graph search you can view all their photos regardless of their privacy settings. This works even for friends who have put you on a ‘limited’ profile.
Your boss/ex/grandma is probably checking out your private photos right now.
