Image generation system, communication apparatus, methods of operating image generation system and communication apparatus, and storage medium

An image generation system functioning as a cloud browser and capable of communicating with a communication apparatus, the image generation system comprising:

• one or more memories;
• and
• one or more processors in communication with the one more memories,
• wherein the one or more processors and the one more memories are configured to:
• receive an operation instruction with respect to a web page from the communication apparatus, wherein the operation instruction includes information indicating an attribute of the operation instruction;
• transmit, to the communication apparatus, predetermined information when the operation instruction is a press for file selection, wherein the predetermined information includes information of a pressed element and information indicating being in a file selection mode;
• receive file structure information transmitted from the communication apparatus based on the information indicating being in the file selection mode;
• reproduce a visual representation of a file structure that corresponds to that of the communication apparatus by expanding a folder and generating a group of files based on the file structure information, wherein the group of files are a group of zero-byte files, and transmit the visual representation to the communication apparatus;
• receive, from the communication apparatus, information of coordinates of a press of a user with respect to the visual representation;
• identify information on a file present at the coordinates of the press;
• transmit the information of the identified file to the communication apparatus, wherein the information of the identified file includes a file name;
• receive data of the identified file transmitted from the communication apparatus;
• replace the group of zero-byte data files with the received data of the identified file;
• and
• generate a rendering result that reflects the received data of the identified file and transmit the rendering result to the communication apparatus.
