Twitter adds photo tagging
Twitter has added a new feature to its mobile app. Twitter now allows users to add up to four photos in a single tweet and tag people that are in the photos.
You are able to tag up to 10 other people in a single photo. The tags will not affect the 140 character limit. If you are tagged in a photo, then you will receive a notification. Notifications are customizable under the Settings menu.
