An information managing system for browsing or transferring images between apparatuses is connected to a network. In this system, an information storage apparatus such as an image pickup apparatus, an information managing apparatus such as an image server, and an information processing apparatus or client computer such as a PC are interconnected by the network. The information storage apparatus uploads only related information such as an index of image data stored therein to the information managing apparatus to publicize the related information on the network. Only when the information processing apparatus for browsing the public information issues a transmission request for original information, the original information is transmitted from the information storage apparatus to the information processing apparatus.
