New description:

 Summary: if link to image ends with string like

 "YYYY/MM/filename.ext"

 and there are image files in MEdia library residing in

 /wp-content/upload/YYYY/MM

 then some of those files will be used to generate "responsive image"
 feature, adding srcset/sizes attributes

 Example 1: On WordPress site http://example.com, document contains markup
 like

 <img src="/wp-content/uploads/YYYY/MM/filename.png">

 where the above file is *not* part of Media library (it just resides in
 that folder). srcset is added with link to (arbitrary selected?) image
 file within that folder.

 Expected behaviour: no srcset/sizes should be added.

 Example 2: On Wordpress site http://example.com, document contains markup
 like

 <img src="http://cdn.example.com/wp-content/uploads/YYYY/MM/filename.png">

 where cdn.example.com is *not* an alias for example.com, but altogether
 external resource

 Once again, srcset is added with link to (arbitrary selected?) image file
 within  folder YYYY/MM in Media library.

 Expected behaviour: no srcset/sizes should be added.
