Due to the abundance of relatively low-powered (in terms of CPU power) and low-bandwidth (as for mobile devices like Chromebooks) devices, it is important for web developers to keep an eye on a website’s images. Serving large images to mobile users with small screen sizes and low bandwidth is unnecessary and may make some users leave the website early, while it’s still loading.
HTML5’s srcset and sizes attributes enable webmasters to give hints to the browser for it to decide which image resource to load, e. g. from a set of different resolutions. However, keeping all images available in a lot of different resolutions is a tedious task for today’s webmasters.
