Image communication apparatus which uses a signal provided by a communication network to optimize the quality of image data for communication

There is described an image communication apparatus and an image communication program capable of transmitting image data with the output attribute conforming to the communication charge, and capable of determining the image data output attribute at an earlier phase. The image communication apparatus includes: a signal judgment section which judges specific signals received via a network; an output setting section which sets output attribution of image data to be transmitted for a destination via the network in accordance with a judgment result by the signal judgment section; a network switching section which switches a network for transmitting the image data to the destination in accordance with the judgment result by the signal judgment section. The signal judgment section judges the specific signals after requesting connection with the destination to the network and before establishing the connection with the destination. The specific signals represent charge information about communication with the destination.
