Program and communications system

A communication system comprising:

• a communication terminal device having a display panel, an input interface, a first communication interface connected to an Internet, and a first controller;
• and
• a server having a second communication interface connected to the Internet and a second controller, wherein
• the first controller executes:
• acceptance processing of accepting an input of information indicating a component, a house, or a customer through the input interface;
• and
• first sending processing of sending a first request to a communication address indicating the server through the first communication interface, the first request including specific information according to the information accepted by the acceptance processing and a return request of requesting a return of construction information,
• the second controller executes:
• acquisition processing of receiving the first request through the second communication interface, and acquiring the construction information associated with the specific information from a memory, based on a fact that the return request is included in the first request;
• determination processing of determining whether the construction information acquired by the acquisition processing includes a construction photograph;
• second sending processing of sending a first response having the construction information including the construction photograph through the second communication interface, based on determining that the construction photograph is included;
• and
• third sending processing of sending a second response having solicitation information and the construction information through the second communication interface, the solicitation information indicating that the construction photograph is solicited, based on determining that the construction photograph is not included,
• the first controller executes:
• first display processing of displaying the construction information on the display panel, based on receiving the first response through the first communication interface;
• second display processing of displaying the construction information and information according to the solicitation information on the display panel, based on receiving the second response through the first communication interface;
• photograph data acquisition processing of acquiring photograph data showing the construction photograph, based on executing the second display processing;
• and
• fourth sending processing of sending a second request including the acquired photograph data to the communication address through the first communication interface, and
• the second controller executes:
• storing processing of storing, in the memory, the photograph data included in the received second request.

A process implemented on a communication terminal device having a display panel, an input interface, and a communication interface connected to an Internet,

• the process comprising the steps:
• acceptance processing of accepting an input of information indicating a component, a house, or a customer through the input interface;
• first sending processing of sending a first request to a communication address indicating a server through the communication interface, the first request including specific information according to the information accepted by the acceptance processing and a return request of requesting a return of construction information;
• first display processing of displaying the construction information on the display panel, based on receiving a first response through the communication interface, the first response being a response to the first request and having the construction information including a construction photograph;
• second display processing of displaying the construction information and information according to solicitation information on the display panel, based on receiving a second response through the communication interface, the second response being a response to the first request and having the solicitation information and the construction information not including the construction photograph;
• photograph data acquisition processing of acquiring photograph data showing the construction photograph, based on executing the second display processing;
• and
• second sending processing of sending a second request including the acquired photograph data to the communication address through the communication interface.
