1. A method comprising: defining a first portion of a hybrid image file to encode a bitmap image; defining a second portion of the hybrid image file to encode a plurality of images according to a multi-frame format; and concatenating the second portion to the first portion to create the hybrid image file that includes detectable data that is detectable to determine when the second portion encodes one or more alternate images to the bitmap image, wherein the first portion of the hybrid image file enables an application that is not configured to detect the second portion of the hybrid image file to output the bitmap image encoded in the first portion without awareness of the second portion of the hybrid image file.
