How do I remove posters from my contacts in iOS 26?

If someone has chosen their own poster for themself on their iPhone, that is how it will appear in your contacts and it's not something you can change.

Sorry, but that horse has left the barn. No way to revert to it.

What do you mean by "poster?" Can you please provide more detail?

We are just other Apple users in this community forum. Apple does not share any future plans with us so we don't know the answer to your question.

Honestly, no, and frankly I don’t care. Huge non-issue as far as I’m concerned.
