A slideshow is an online series of still images used to tell a story, usually with captions and often with audio. Slideshows (the term pays homage to those old transparencies shown with carousel projectors) may include interviews, natural sound, narration by a reporter or photographer, and even music.Although slideshows can be created in various programs, Soundslides has become the standard tool for journalist-produced audio slide shows, owing to its low cost and ease of use.
