In JR for an image we specify an URL. This means JR will get the default image from the server. But, browser will add some headers to the request and ask for optimal image https://www.keycdn.com/blog/client-hints.
When we build the report we know DPI, JR could automatically add this hints and get a smaller image.
This could reduce bandwidth utilisation, reduce download times, report size and increase speed.
