The collages will be packaged in video presentations of photos of friends and family that have been previously been posted on Facebook. The photos are picked out by automated technology, although each Facebook user will be able to delete some and select other pictures instead.
The videos won't be seen by anyone else unless a user decides to share the presentation.
Most Facebook users should start seeing the videos at the top of their Facebook feeds by noon Thursday, which the Menlo Park, California, company is hailing as "Friends Day." It coincides with the 12th anniversary of Facebook CEO Mark Zuckerberg starting the social network in his Harvard University dorm room.
