Hi Paul
I looked your phone up on the net and I think you may only be able to do it using MMS (MultiMedia Messaging Service) or Email if you have a phone plan that allows that your phone has the capabilities according to this website. If that is not possible I think you are completely stuck.

The phone I just got through Optus Prepaid is only $50 and it has great features that you might find useful it has bluetooth , usb connection and has a 2MP camera and takes a micro SD card to boot a great deal maybe you should consider it for future use.
