Need help with Sony Ericsson C905?

Ive had the sony ericsson C905 for about 3 months now, and Ive never had any problems, I love the phone especially for the camera. But for some reason the last few pictures Ive tried to send to someone, its resizing them to a way lower resolution and I dont know why, no settings have been changed or anything and I know there's enough memory cuz I have a memory card. It used to send them full size which is 3264 x 2448, but now its started resizing them to 640 x 480. Which means there crap quality. Does anyone know why this is happening? Any help would be appreciated :)
Oh and by sending I mean in a text message
