Abstract: The invention is in the technological field of imaging, to supply a multimedia application on a terminal (10), using a programming agent. The invention relates to a process to supply, on a terminal (10), a multimedia application using a programming agent (36), comprising the following steps: automatically send from an applications server (20) to the terminal (10) a digital data medium (31) containing the programming agent (36), based on the digital data of a first message initially sent from the terminal to said applications server; automatically extract, from the terminal (10), the programming agent (36) from the digital data medium (31); automatically save the programming agent in the terminal. The invention also relates to an imaging system in which the programming agent manages the communication of digital data among terminals (10) and service platforms (30) that can inter-communicate. The invention is preferably implemented in networks that require the use of mobil terminals.
