A portable electronic device comprises a display facing in a first direction, a video camera facing in a second direction substantially opposite to the first direction, and a wireless communications receiver operable to receive supplementary image data from a remote image source, the supplementary image data comprising an indication of where a supplementary image is positioned with respect to a reference image. The portable electronic device is arranged in operation to display a captured image from the video camera on the display of the portable electronic device. When the captured image comprises all or part of the reference image as displayed on a separate display associated with the remote image source, the portable electronic device is arranged in operation to display the supplementary image positioned with respect to the reference image, instead of the corresponding part of the captured image.
