摘要

According to the present invention, when a first frame is selected from among a plurality of frames constituting a first image stored in the third client terminal by a user of the third client terminal among a plurality of client terminals, the third client When the frame image for the first frame is received from the terminal and at the same time a registration request for the chat session of the first frame is received, a second chat message including the frame image for the first frame is generated and the a second message registration unit for registering the second chat message in a chat session; an image request unit for requesting transmission of a first image file of the first image and sequence number information of the first frame of the first image to the third client terminal when the second chatting message is registered; When the first image file and the sequence number information of the first frame of the first image are received from the third client terminal, the first image file and the sequence information of the first frame of the first image are exchanged with each other an image storage unit for storing the corresponding image in the file storage; and when a frame image for the first frame included in the second chatting message is selected by a fourth client terminal among the plurality of client terminals, a frame image for the first frame is selected from the fourth client terminal When a signal is received, the sequence number information of the first frame for the first image file and the first image is extracted from the file storage, and then, the first image file and the first image for the first image are extracted to the fourth client terminal. Simultaneously with transmitting the sequence number information of the first frame, a video file playback command to the fourth client terminal - The video file playback command causes the fourth client terminal to transmit the first image according to the sequence number information of the first frame is a command for controlling to reproduce from the first frame - including an image transmission unit for transmitting.
