On June 6th, 2012, Matthew Prince announced the release of Mirage, an automatic image loading management system designed to maximize website performance. Images make up more than 50% of a typical website's data, and tools like CloudFlare's Polish can reduce their size. However, not loading unnecessary images would be even better for performance. Mirage addresses this by only delivering the necessary images based on the visitor's viewport, device type, and network connection. It also optimizes images to the appropriate size and resolution, reducing bandwidth usage and improving mobile performance. While it requires a paid subscription, Mirage can significantly enhance website responsiveness and efficiency when combined with Polish.
