Saving resources: Show image with 'Play' button overlayed, embed player (with autoplay property) when image is clicked.

[iadj]

When you want to embed a large amount of URLs on a single page, in a social feed or blog for instance, you will get a large amount of resources and requests. This is not ideal for mobile and page load speed in general.

It'd be great if there's a setting that allows us to embed only the URL's 'og:image' property, overlayed with a Play button, and then load the player iframe only if the button is clicked.
