Use placeholders when building layouts before final imagery is ready — design mockups, front-end prototypes, component libraries, client presentations. Dummy photos make the layout feel real without distracting from structure evaluation. Switch to real images before launch; placeholder services add runtime HTTP dependencies and don't compress for production. Alternative: lorem picsum is the best-known dummy photo API but lacks colored rectangles and avatar variants.
