A relaying device (60 and 200) comprising: a network interface configured to connect to a network; a data selection instruction information reception module configured to receive, via the network interface, from an image processing device which is connected to the network, data selection instruction information identifying selection data selected by the image processing device from among data stored in a server device (100, 110) configured to store data in a document file format which cannot be interpreted by the image processing device and data in an image file format which can be interpreted by the image processing device and connected to the network; characterized in that it further comprises a data conversion module configured to receive, from the server device (100, 110) via the network interface, data type information indicating whether the selection data identified by the received data selection instruction information is data in a document file format or data in an image file format; a selection data reception information transmission module configured to transmit selection data reception information to the image processing device via the network interface if the selection data received by the selection data reception module is data in an image file format, the selection data reception information being for causing the image processing device to access the server device (100, 110) and to receive the selection data from the server device (100, 110); a selection data reception module wherein the selection data reception module is configured to receive, from the server device (100, 110) via the network interface, the selection data identified by the received data selection instruction information and the data conversion module is configured to execute conversion processing if the data type information indicates that the received selection data is data in a document file format, the conversion processing receiving the selection data from the server device (100, 110) and converting the selection data into converted data in an image file format which can be interpreted by the image processing device; and a converted data reception information transmission module configured to transmit, to the image processing device via the network interface, converted data reception information for causing the image processing device to receive the converted data in the image file format from the relaying device, if the selection data received by the selection data reception module is data in a document file format. a network interface configured to connect to a network;
