Why Use Placeholder Images?
During web development and design mockups, you often need images at specific dimensions before the real assets are ready. Placeholder images let you build layouts, test responsive breakpoints and present prototypes without waiting for final photography or graphics. They also serve as fallback images, loading spinners and test assets in automated testing.
