A bunch of gifs were exchanged in a group chat including one from me. The other users are iphone users. I received a message "so-and-so 'liked' an image". How can I see which image was "liked?"
You, on Android, cannot. Messages to/from you are via the SMS/MMS system, which does not support such features. All the iPhone people are using Apple's iMessage instant messaging service, which supports many features that SMS does not support.
