[Feature Request] Image quality/resizing

[tr7zw]

Is your feature request related to a problem? Please describe. Some mangas have pages in really high quality, which becomes an issue when loading them on a phone via mobile data and a vpn connection to the home server(with bad German internet 😞 ). For example there is no point in loading images with a width of 1584px, when the phone screen is only 1080px wide. Adding a toggle to activate some kind of "data-saver" mode that downscales images server-side to a more reasonable image and file size would help to improve mobile load times, and reduce data usage.
