Recent years have witnessed emergence of a new family of imaging devices known as digital-image senders. These devices allow users to digitally scan a hardcopy document, and send the resulting digital image data via a communications network to other devices on the network. One problem that the present inventors recognized with these devices is that they do not provide a convenient way for users to add user-specific information to the images they send. Accordingly, the inventors teach, among other things, an exemplary method that includes providing image data, determining an identity of a user associated with a communications device, and defining a modified version of the image data, based on the determined identity of the user.
