I am having an issue when using images that are 7680px wide not working on iOS devices. iOS requires a max of 4096. Is there a way to have this plugin serve a 4096px wide image when a visitor is using a mobile device?
Regarding this thing, you may need to do a lot of changes to our plugin file. If you want, you can resize the image before uploading but it will make the desktop and mobile have the same size as a smaller size. Let us know if you have further questions.
