Not sure about the main issue, so many things could cause that one.
But for this if you can receive thenthe best thing to check is your camera settings. More than likely the photos are too large in size to actually send. You can open your camera, press your Menu button, select camer otpions or options. Then change Picture Size to Medium, Picture Quality to Normal and then take a photo and send it to your self as MMS.
