Situation:
Imagine having a web app that shows an error message when trying to perform an action but fails due to a connectivity problem.
The error dialogue has a CSS class with a background image that can't load because of the connection issue, resulting in a weird-looking dialog box.
Is there a solution to preload the image so it is accessible even without an internet connection?
One way to optimize image loading on your website is by registering a service worker and caching the images. This way, when an image request comes in, you can quickly respond with the cached image. Check out this link for more information on using service workers.
