A system includes a medical diagnostic imaging apparatus configured to generate medical images of subjects and to generate connection verification support information to be used by a connection-target apparatus to verify connection with medical diagnostic imaging apparatus; a peripheral apparatus expected to be connected with the medical diagnostic imaging apparatus via a communication network and configured to operate the medical images generated by the medical diagnostic imaging apparatus; and a web server apparatus configured to record the connection verification support information generated by the medical diagnostic imaging apparatus. The peripheral apparatus verifies connection with the medical diagnostic imaging apparatus by using the connection verification support information acquired from the web server apparatus.
