Facebook has apologised after a new feature inviting users to review a collection of their 2014 highlights caused some to be confronted with pictures of their recently deceased family members and friends.
The social-media site began inviting users to look at their "Year in Review", a chronological collection of photos picked automatically from their profile, just before Christmas.
It compiles their "highlights" by selecting the posts and pictures that provoked the most responses - but for many users, this dredged up highly unpleasant memories.
Eric Meyer, a web-design consultant from Cleveland, Ohio, was confronted by a picture of his 6-year-old daughter, Rebecca, who died of brain cancer this year, alongside the jaunty tagline: "Eric, here's what your year looked like!"
In a blog post, Mr Meyer said he found the image - which appeared against a background showing people celebrating - "jarring" and "wrong".
