Abstract: When an E-mail address is inputted, it is judged whether the E-mail address is an address registered in advance. If this judgment result is positive, an image read by a scan section is stored in a server 111, and an E-mail, with a URL indicating a location of the stored image, addressed to the E-mail address is generated. If the judgment result is negative, an E-mail addressed to the E-mail address and with an image read by the scan section is generated. The generated E-mail is transmitted.
