Abstract: An image stream of static graphic images and a corresponding audio stream (e.g., a comic book image stream and an audio narration stream) are simultaneously rendered. One or more images from the image stream, which are each associated with time information relative to a timeline of the audio stream, are downloaded to the client device. A page is assembled from the images and is assigned time information relative to the timeline of the audio stream on the basis of the time information for the images. A portion of the audio stream including a time offset corresponding to a position on the page is downloaded to the client device. The page and the portion of the audio stream are simultaneously rendered on the client device by using the time information for the images or for the page, the portion of the audio stream being rendered in dependence upon the time offset.
