If you want to see private Facebook pictures, the only real way is to become friends with that person. BUT I have used a really simply trick to see private Facebook photos of my ex-boyfriend, and I'm pretty sure it'll work for you too:
How to see private Facebook photos and ALL profile activity
- Go to the account in question
- Check out their friends list, go to "see all" and scroll down a bit (Facebook sorts friends by how often a user engages with them, so you want to pick someone a little bit obscure, and not too obvious).
- Find a profile that has a lot of images visible (not set to private), and start recreating that profile with a fake account (use the exact same name, profile picture etc...)
- Send a friend request to the person who's photos you want to see, and also a message saying:
"hey, my account got hacked by some loser, so I'm adding everyone on a new profile. Please don't click on any links sent from my old profile as they could hack you too. Thanks!"
- Try to make the message sound as believable as possible and I can GUARANTEE they will add you back.
- You now have access to all their private photos, status updates, the lot!
