1.- we are going to clarify some points: this is a mobi file for kindle products we do not need images beyond 3200x it is electronic ink 2.- I don't know why people want to look for manga images beyond 3200x or 5000x ¡¡¡ when your mobile, ipad or tablet only supports full hd at most 4K unless you see the manga in a 60-inch smart 4K and in position vertical haha 3.- Why don't I use PNG files instead of jpg file? simple when you create a manga with png files you lose on the screen margin something that does not happen in a jpeg file that the image can fill the entire screen how kindle adjust all screen if you like it feel free to download it and please seed and share thanks and thanks fakku by upload the zip file and report mistakes please
