Preventing downloading images or objects until they are visible in the viewport - WHATWG

This is an interesting discussion on the possibility of standardizing a way to request that the browser not load or delay loading images or objects. The key point that developers from the BBC stress is that for a non-zero number of users, JavaScript fails to run yet is enabled, so having a way to ensure they can still view images is important. As excellent as they can be, relying on on JavaScript solutions and serving non-functional markup can lead to broken pages in those cases since we don’t truly control our webpages.
