Abstract
An image communication system including electronic-mail apparatuses each having a function to add image-file processing information to an image file attached to an electronic mail. The image processing capability of each apparatus is examined in advance. In a transmitting-side apparatus, an image file is generated in accordance with the capability, and an electronic mail, to which the image file is attached, is transmitted to a receiving-side apparatus. Further, if the image file attached to the transmitted electronic mail cannot be processed by the receiving-side apparatus, the receiving-side apparatus notifies the transmitting-side apparatus of clarified cause of processing failure, further, transmits its image-file processing capability and the unprocessed transmitted electronic mail to the transmitting-side apparatus. Thus, efficient image-file transmission/reception can be performed.
