Why can't I send written text with a picture?

[AC Question]

Cannot send written text with a picture

Just got the Galaxy Edge. No problems until today. When I try to send a picture with a text message it will only send the picture. If I chose a picture from my galley to send via the messaging app it defaults to my contacts. When I choose one the only function is "done" when I click it the picture is sent with no option to write a message. If I already have a text started and use the attach
icon it will send the picture only. I have sent the text messages with pictures attached with this phone up until today.
