There are a couple ways to get pics into your messages. Copy and past them is another way besides adding them by creating a new message. Just copy and paste the pic into the body of the message. You can do this directly from your photos. Just like above, select the ones you want to go with the message and then just select copy. And then paste them into your ongoing message. Hopefully I didn't miss this being said already. Forgive me if I did. Have a good day.
