a display control unit configured to display an image corresponding to the image data in response to receipt of the image data through the display device side communication unit.

2. The network system according to claim 1, wherein the reading device side communication unit transmits the image data directly to the image display unit without storing the image data in a storage device.

3. The network system according to claim 1, further comprising a data storing device connected to the network,

wherein the display device side communication unit of the image display device further performs data communication with the data storing device, and an image selection instruction is inputted through the instruction input unit of the image display device,

wherein the data storing device comprises:

a storing device side communication unit configured to perform data communication with the image display device;

a storage device in which image data is stored;

a data extraction unit configured to extract stored image data designated by an image selection instruction from the storage device in response to receipt of the image selection instruction; and

a storing device side communication controller configured to transmit the stored image data extracted by the data extraction unit to the image display device through the storing device side communication unit,
