Claim One:
1. A communication terminal device comprising: a processor; and a memory configured to store computer-readable instructions that, when executed by the processor, cause the communication terminal device to: receive a material image and corresponding first identification information transmitted from a communication terminal device via a network, the material image being an image of a material, and the first identification information identifying the communication terminal device that has transmitted the material image; receive a captured image and corresponding second identification information transmitted from a communication terminal device via the network, the captured image being an image captured by a camera and different from the material image, and the second identification information identifying the communication terminal device that has transmitted the captured image; determine whether the material image and the captured image have been transmitted from the same communication terminal device by comparing the first identification information with the second identification information; and display, when the result of the determining indicates that the material image and the captured image have been transmitted from the same communication terminal device, the material image and the captured image on a display device at positions at which at least a part of the captured image overlaps with at least a part of the material image or at positions at which an outer edge of the part of the captured image abuts an outer edge of the material image.
