 * Activating this adds the src-set as data-src-set so it doesn’t pass validation
   as sizes is still added causing
 * > the sizes attribute may be specified only if the srcset is also present
 * other settings,
    picture fill, Keep IMG SRC [x]

 * Yes but then you lose the advantages of the Lazysizes I think. Lazy loading for
   images can’t be “valid” unfortunately, but I would be you I wouldn’t care about
   it much 🙂

 * so they can’t be lazy & validate?
 * Would be worth adding a not to this option like on the other settings too to 
   save others time figuring out what’s going on.

 * No, for le lazy to work you can’t have the SRC. I mean if you keep the SRC it
   works, but the normal image will be loaded in a non-lazy way, and the Retina 
   will be loaded in a lazy way if required.

 * Yes, I will add a note in the description in the options.
