Ada67, let's get your picture messaging working! As soupcannon suggested, you'll need to make sure MMS messaging is turned on in Settings, then Messaging. If this is already turned on, verify you are able to send picture messages. Try sending yourself one and see if you receive any errors. Dial *228 option 2 and reboot your phone. If no change, reset your network settings by going to Settings, General, Reset, Reset Network Settings.
Let me know if you need further assistance.
