Dummy image placeholders are temporary images that are used as a stand-in until the final image is available. These placeholders are also referred to as dummy images, filler images, or placeholder images. Dummy images are often used in wireframes, mockups, and prototypes to give a visual representation of where the image will be placed, how it will fit into the design, and what size it should be.
In conclusion, dummy image placeholders are an essential tool for web designers and developers. They help to facilitate the design process, save time and effort, visualize the final product, provide flexibility, and increase collaboration. There are different types of dummy images available, including generic images, stock images, grayscale images, and lorem ipsum images. By using dummy images, designers and developers can create a better website design that effectively communicates the intended message to the audience.
