Placeholder image generation.

Placeholder images, also known as dummy images or filler images, are temporary visual placeholders used in web design and development to demonstrate the structure and layout of a website or application. Placeholder images are typically generated automatically through specialized software or online tools, and can be customized based on size, shape, color, text, and other parameters. Placeholder images can be useful in various contexts such as prototyping, testing, and placeholder content while waiting for actual content to be added.
