👋🏽 About image CDN

An image CDN (Content Delivery Network) is a type of CDN (Content Delivery Network) that is optimized for delivering images and other visual content, such as videos and graphics. It uses a network of servers located at strategic points around the world to deliver images to users as quickly and efficiently as possible.

An image CDN can help to improve the performance of a website or web application by reducing the amount of time it takes for images to be downloaded and displayed to the user. This can improve the user experience, particularly for users who are accessing the site from different locations around the world.

Image CDNs typically provide features such as image optimization, which can reduce the file size of images without sacrificing quality, and image resizing, which allows the images to be delivered in the appropriate size and resolution for the user's device. They may also provide security features, such as encryption and authentication, to protect the images from unauthorized access.
