This is so untrue. If Facebook ever released information on who looked at your profile and picture, people would go crazy.
Also, dude has still not answered my message even though someone posted a video on his wall and he commented on it.

WHY IS HE IGNORING ME? Now I feel like the weird one. I check his facebook like every hour. I noticed he was using a mobile device to update his status, so I was thinking maybe he just hasn't seen I've sent him a message. If he watched a video though, I'm pretty sure he's seen my message.
This was probably his plan all along.
