A system and method are presented to allow text-based communication between users concerning an image in the form of an image-message. The originator of the communication uses a mobile device app to select an image and enter appropriate text. The recipient mobile device receives an image-message, and then displays the text superimposed over the image. The recipient can enter reply text, which will then be shown superimposed over the image as part of a message stream. The recipient can also alter the image, with the altered image being transmitted back to the originator. When the reply message is active, the altered image is displayed behind the message stream. The user can select an earlier message in the stream to view the image associated with that earlier message.
