They would provide the photo. You choose your photo and everyone else gets it which is already true with the small contact photo and name which are shared automatically.
I see! That's better/easier. I hope they've come up with something that still looks decent for the majority of my contacts who don't have or share a contact photo or who (shock) don't use an iPhone.
I know this is cynical but might a degraded experience for your Android contacts be a significant plus of this feature? (edit: I mean for Apple Inc, not for the end user). Like green bubbles.
Maybe, to the extent that people care enough about it to bug their android-owning contacts about it. I don't think that will be a very large number of users, especially since this is pretty trivial compared to the features you lose in iMessage group chats by adding SMS contacts.
Yep, I'm definitely not going to photobomb people with this.
