Comment (by celloexpressions):

 #51058 is a slightly different result of this same problem.
 `attachment_url_to_postid()` should be able to identify any WordPress-
 generated files that are related back to the same attachment post/file.
 Or, there should be a separate function that serves this purpose.

 There are several situations where plugins or themes are only able to
 access a single attachment-related URL (ex. one scaled image size), and
 they need to find the attachment ID to access other attachment data.
