  Loading images progressively using Gaussian blur

The popular online publishing platform Medium has adopted an impressive image loading mechanism -- pure color - blur image loading - real image loading. Since images on Medium usually have high definition, it takes much time to load an image and hence brings a bad user experience if rendering the image after it's completely downloaded. The solution Medium comes out is to preload an small image when the real image is being loaded.  On Medium, the HTML code will have below pattern ...
