I would recommend not to use the soundcloud logo for "uncloud your data" unless you have asked https://soundcloud.com wether it is ok :)

Some browsers like chrome support this functionality natively by setting the image attribute loading="lazy" (https://web.dev/native-lazy-loading/) You could improve your library by adding a check wether the browser supports it natively, if yes use the loading attribute, if no use the visibility observer
