Um

via pc or browser, then screenshot/printscreen

i dont know if this works in every site or whatever but if your in the web with a pc or laptop , just left click then click the save as i donk know the details but i think it downloads the whole webpage pictures included and everything just go to that folder where the pictures are downloaded just tested it with webtoon it worked if you dont want to go screenshotting then you could do this trick

Thank you
