Responsive web design provides a solution: "develop once, works in every device." However, still it downloads multi-MB images and re-sizes them based on device screen resolution. Retrieving optimized images from the server, based on device (desktop, tablet, phone) and the device's internet connection (fiber, broadband, mobile), has always been an open problem. Recently, a number of freelance developers are tackling this with a new HTML element, <picture>, which informs the web browser to download optimized images from the server. The tag will be featured in Chrome and Firefox later this year. Will this finally deliver us faster web browsing on mobile devices and an easier web development experience?
