Wget2 already supports it.

Eventually we backport it to Wget1.x.

The HTML picture element provides a way to specify multiple image source candidates. This can be used to e.g. show SVGs on browsers that support it, and PNG fallbacks everywhere else:

  <source type="image/svg+xml" srcset="logo.svg" />
  <img isrc="/img/logo.png" srcset="logo.png 1x, -email is unavailable- 2x, -email is unavailable- 3x" alt="logo" />

If I invoke `wget -r` on a site with this markup however, wget only fetches the src and srcset, not the picture source candidates.
