When I imported and synch'd my contacts (originally in Outlook Express WinXP), some of the imported contacts had "Contact Photos" as part of the contact (I didn't add that). I realize that you can add any contact photo you want to a contact you have. On the S4, if you open a contact, a menu choice is "Share namecard via" which i tried sending to my S3 partner and they receive an attached .vcf contact attachment which imports nicely into their contact list.
The other part of my question was during a texting session, the person on the S3 doesn't see and small Contact photo icons beside the text but I see them on the S4. Is that a different functionality included in the S4?
