Lisa, a 14-year-old girl, from the USA, used an app to make her dream come true. She tried it out on a childhood photo of her mother. Guess what? In the old photo, her mother, a little girl at that time, began to smile at her. It sounds like Harry Potter's moving photos, doesn't it?
It's not magic, but a real thing. The app that Lisa used is called My Heritage. By using an AI（人工智能）technology, the app allows users to animate（使……成为动画） still photos. The technology is the work of D-ID, an Israeli（以色列的）company. At the beginning, they designed it to bring photos of people in history to life. This means you can see them blink（眨眼）, and even turn their heads. Now Americans find it fun and many are giving it a try with their old photos. Millions of users have watched their loved ones come to life in old photos.
The service is easy to use. First download（下载）the app. Next, click（点击）on the menu and choose "photo" from the list. Then upload（上传）the photo you wish to animate. The AI technology will take around 20 seconds to work its magic on the photo. Then it's done!
