Effortless Responsive Images with LazySizes and Umbraco

Slimsy v4.0.0 requires Umbraco v10

Slimsy v3.0.0-beta1-beta3 requires Umbraco v8.1.0-v8.5.x

Slimsy v3.0.0-beta4+ requires Umbraco v8.6.0+

Slimsy v2.0.0+ requires Umbraco v7.6.0+

LazySizes.js used in conjunction with ImageSharp.Web and the built-in Umbraco Image Cropper will make your responsive website's images both adaptive and "retina" quality (if supported by the client browser).

Slimsy includes lazysizes.min.js

Below is an example of how easy it is to render a multi source picture tag with a fallback image using v4 in Umbraco v10

<slimsy-picture media-item="@person.Photo" width="323" height="300" css-class="myClass" render-lqip="true" render-webp-alternative="true"></slimsy-picture>
