A method and system for combining subsequent data in a communication stream including receiving an indication of a selection of a first image in a communication thread and identifying a user attribute setting associated with the first user. Based on one or more composite image generation rules, the method includes determining that the selected first image is compatible for converting into a composite image. The method further includes accessing a user attribute setting associated with a second user and generating the composite image based on the selected first image and the user attribute settings of the first and second users. The generated composite image is then caused to be displayed in the communication thread.
