Disclosed herein are a system and method for providing a 3D image production service. The system includes a first DataBase (DB), a user terminal and a service server. The first DB stores information for constructing 3D background screens, web site content information for producing 3D images, and personal information, information about a 3D background screen constructed by a user, and web site information using a 3D image. The user terminal maintains an on-line state through login upon booting, displays a 3D background screen after parsing and rendering 3D data and sets a web site using a 3D image. The service server authenticate a user while maintaining an on-line state with the user terminal, provides the user terminal with relevant tools when the user requests a configuration for managing a web site using the 3D background screen and the 3D image, stores the configuration for managing the web site using the 3D background screen and the 3D image, which is constructed by the user, in a corresponding user storage space of the first DB, and synchronizes information stored in the user terminal with information stored in the first DB.
