Sorry to hear that, milescrystal. Let's do some investigating. What error are you receiving when trying to send picture messages? Are you able to receive them? What's the make and model of your phone?
Does that message includes a error code or number? Also, we'd like to make you aware that If user attempts to load an unsupported file type, they will get an error message. Please try to send a different picture or a different video and let us know if it works, @milescrystal
