When viewing a photo message from a friend via direct message, you can now reply with a sticker, along with custom text and doodles. Moving and resizing is also applicable, as you can remix photos back and forth for a fun visual of your conversation.
Additionally, users can now control replays by choosing “One View” for messages you want your friends to only see once. For everything else, choosing “Allow Replay” lets your friends have more time to view your messages, while this option also provides your friends the ability to tap and hold to pause.
These updates are available for Instagram version 24 in iOS and on Android.
