Lorem Picsum is a free, easy-to-use placeholder image service created by David Marby and Nijiko Yonskai that provides stylish, customizable stock photos for developers and designers.

The main features and capabilities of Lorem Picsum include:

• Simple Dimensions & Sizing: Request placeholder images of any desired width and height directly within the URL structure (e.g., /200/300 or /200 for square images).

• Specific & Seeded Images: Retrieve a specific photograph by specifying its image ID (/id/{image}) or request consistent random images using a custom seed string (/seed/{seed}).

• Visual Filters & Adjustments: Apply a grayscale filter (?grayscale), add image blur with adjustable intensity levels from 1 to 10 (?blur=2), or combine multiple parameters into a single request.

• Format & Cache Control: Request specific file formats such as .jpg or .webp, and use a ?random query parameter to prevent browser caching when loading multiple images of identical dimensions.

• API List & Metadata Endpoints: Fetch paginated image lists via /v2/list (with page and limit parameters) or inspect specific image details, author info, and dimensions via /id/{id}/info.
