Facebook, whose members upload more than 100 million photos every day, is testing a feature designed to streamline and increase the tagging of people in pictures.

When a photo is uploaded, Facebook will now detect the presence of people in it and prompt the user to identify them by name, one by one, a process that until now has been manual.

"With this new feature, tagging is faster since you don't need to select a face. It's already selected for you, just like those rectangles you see around your friends' faces when you take a photo with a modern digital camera. All that's left for you to do is type a name and hit enter," said Sam Odio, Facebook photo product manager.

More improvements to Facebook's photo management and sharing features are in the works, according to Odio. Uploading photos is a very popular activity on Facebook - about 99 percent of its active users have posted photos on the site.
