A filmstrip is a sequence of still images arranged in a linear order, traditionally on a strip of photographic film. Each frame on the strip represents a single moment or scene, and when viewed in rapid succession, these frames create the illusion of motion. Filmstrips were widely used in early cinema, education, and animation to tell stories or present information visually. In digital contexts, the term can also refer to a horizontal or vertical row of thumbnail images, allowing users to preview and navigate through a collection of visuals efficiently.
