Hello fangs,
That sure can be irritating to not have your device work as it should. I need additional information so that I can better assist you. Which picture are you inquiring about? Is it the profile picture or picture messages are sending duplicates?
Are you using the stock text message application or a third-party text message application. I would recommend to delete the contact (s) that this is happening with and add it back again. Additionally, I would delete the text message thread in the message folder of that particular contact.
Looking forward to your reply.
Thank you,
Lena A.
