title: How to force caching of 10mb+ images so they never get reloaded?
body: <p>I have a site which has 10mb+ of images (1000+ pngs) that have to be loaded before it starts. My current approach is loading every image in a hidden tag. How can I ensure that a client that accesses the site once/month, for example, will never have to download it all again?</p>
