an obtaining section to obtain first image information of a first resolution corresponding to the request to send image information received at the receiving section;
a determining section to determine whether there is a client terminal device which connects a display device with a second resolution, among the at least one of the plurality of client terminal devices from which the request was received by the receiving section, according to the identification information of the at least one of the plurality of client terminal devices received by the receiving section and the identification information stored in the storage section;
a server resolution conversion section to convert the first image information of the first resolution obtained by the obtaining section into second image information of the second resolution, in case it is determined that there is a client terminal device which connects a display device with the second resolution, among the at least one of the plurality of client terminal devices from which the request was received by the receiving section, according to the determining section; and
an image information sending section to attach resolution information that indicates that the resolution of the second image information is the second resolution to the second image information of the second resolution that was converted by the server resolution conversion section, and to send the resolution information and the second image information to the at least one of the plurality of client terminal devices,wherein the plurality of client terminal devices comprise;
a setting section to set a screen resolution of the display devices connected to the plurality of client terminal devices;
a screen resolution sending section to send the screen resolution set by the setting section and identification information of the plurality of client terminal devices to the server device;
a client resolution conversion section to convert the second image information attached with the resolution information that was sent from the image information sending section, so as to comply with the screen resolution of the display device connected to the plurality of client terminal devices, according to the resolution information; and
a display control section to display an image information converted by the client resolution conversion section on the display device,wherein the plurality of client terminal devices are capable to connect with a first display device with a screen resolution of the first resolution, or a second display device with a screen resolution of the second resolution, which has a lower resolution than the first resolution.
