Messenger has introduced a new feature that allows users to display multiple photos as stacked thumbnails in chat streams. Tapping on these thumbnails reveals a comprehensive view of all images, enabling likes and comments directly from this interface. This update builds on the Shared Album option introduced earlier for group chats, expanding the photo display functionality to all chat interactions. The enhancement aims to foster a more interactive environment and increase user engagement within the app. The update is currently being rolled out in the latest version of Messenger.
