One can add a photo to a contact in mobile phones for long time already. I guess it was already possible when phones where just phones, not "smart" at all. But I, as many others, did not care about this.
I just discovered that most of contacts in my address book do have a
photo or a logo (if contact is not a person). And I really like this.
Moreover, I do not like that some of the contacts do not have a photo.
I did not noticed when this change happened with me, but it did.
Now, when a contact in my address book does not have a photo and I cannot find one (there are such persons, really) I feel disappointed.
