ion-img
Img is a tag that will lazily load an image whenever the tag is in the viewport. This is extremely useful when generating a large list as images are only loaded when they're visible. The component uses Intersection Observer internally, which is supported in most modern browsers, but falls back to a setTimeout when it is not supported.
