Does the name of an image downloaded from Facebook (often numbers) represents something or are mere numbers? For example this name - 178696_436095929768187_414916441_o.jpg.

The name does no longer contain the profile ID of the Facebook user who uploaded the image. This was changed at the end of 2012. Ramandeep S 2013-12-10 03:46:53 Thanks.

It is either a random number, or one which has meaning in terms of FaceBook's databases, but as far as you're concerned it's random.
