You call an API -> it returns some json with content and links to images -> you start doing a new request to load those images -> only when partially loaded (aka on request 2) you will see the progressive images starting to form.

With this: You call an API -> it returns some json with content and links to images and a few bytes for the previews -> you immediately show these while firing off requests to get the full version.

So I'm thinking quicker to first draw of the blurry version? And works for more formats as well.
