Currently lazy loading is applied to the <img> element, even when there are multiple <source> tags for the same image within a <picture>. For a responsive site that may have different images in the viewport based on layout (mobile vertical scroll vs desktop grid for example), a developer will need to decide which layout to optimize for and potentially slow down the performance of the other layouts. A possible solution would be to have a given <source> to have a loading attribute that would override the lazy loading state of the <img> that it is associated with. This is an extension of the original lazyload support:
