Facebook creator Mark Zuckerberg has been left red-faced after photos from his account were hacked and put online.
Hackers used it to highlight a bug in the social networking site. They posted 14 pics with the message: "It's time to fix those security flaws Facebook."
They included shots of him cooking with his girlfriend, holding a chicken, and meeting US President Barack Obama.
Facebook said the glitch had been fixed.
The social networking site said in a statement: "Upon discovering the bug, we immediately disabled the system, and will only return functionality once we can confirm the bug has been fixed."
The bug related to tools allowing users to report inappropriate images.
