A method of decoding coded data provided on a photograph using a reader. The coded data is at least partially indicative of an audio signal and is provided on a photograph substrate in the same area as an image. The method includes steps of scanning the image using a scanner; locating within the image a first target boundary that is spatially displaced from the coded data; locating within the image a second target boundary that is spatially displaced from the coded data and downstream of the first target boundary in a direction in which the image is fed past the scanner; reading the coded data located between the first and second target boundaries; decoding the coded data read by the scanner to obtain an audio signal; and, playing the audio signal through an output.
