An image library is a collection of digital images that can be accessed and used for various purposes, such as marketing, education, or personal projects. These libraries often categorize images by themes, styles, or subjects, making it easier for users to find what they need. Some image libraries offer free images, while others require a subscription or one-time payment for high-quality content. Many image libraries provide licensing options that specify how images can be used, ensuring that creators are compensated for their work. Popular examples of image libraries include Shutterstock, Getty Images, and Unsplash. Users can search for images based on keywords, making it a valuable resource for designers, bloggers, and businesses.
