A communications terminal having an image shooting function allows a user to transmit a shot image as an e-mail attachment more easily and conveniently than in a conventional manner. Before being placed into an image shooting mode, the communications terminal first receives an e-mail address specified by the user as a destination of an image to be shot. Then, at a push of a shutter button in the image shooting mode, the communications terminal shoots an image to generate image data, automatically attaches the image data to an e-mail message, and transmits the e-mail message to the e-mail address specified by the user before the image shooting.
