> Browsers already load images from top to bottom

Is that true? I believe that they kick off the requests to load images from top to bottom, but I don't think they prioritise bandwidth in such a way that downloading image #3 will never make downloading image #1 slower.

That is my understanding as well and I checked mozilla documentation to confirm. [0] That link also covers loading="lazy" attribute for <img> tags, which I've commonly used to defer loading.
