can't send photos

I am using marshmallow and Textra for messages. This is the 3rd message app I have installed and this is the best so far; it will at least "receive" photos but won't send them. It times out in the send mode and then an ! beside the photo and message. I like Textra but what am I doing wrong? I use ATT and all settings are correct. Max
