Abstract: A computer system and computer-implemented method for receiving digitally stored metadata that defines a digital offer including specifying one or more static components and one or more dynamic components; for each of the static components, pre-computing a digital image in an interim raw byte representation and digitally storing the interim raw byte representations corresponding to all the static components; in response to receiving a request to provide a digital offer in real-time on demand: retrieving the interim raw byte representations corresponding to all the static components; for each of the dynamic components, rendering a component image file in real-time on demand; joining the interim raw byte representations corresponding to all the static components and all the component image files corresponding to the dynamic components and creating and storing a single digital image file corresponding to the digital offer; and transmitting the single digital image file to another computer.
