Comment (by leodandesign):

 I've implemented as very simple solution that use preg_replace to remove
 the dimension element of the url and then run the
 attachment_url_to_postid() function.

 {{{#!php
 <?php
 $image = preg_replace('/-\d+[Xx]\d+\./', '.', $thumbnail );
 $image_id = attachment_url_to_postid($image);
 }}}

 It's not elegant, but effective. Couldn't this be dropped into
 attachment_url_to_postid() function to pull get the url using a simple
 pattern instead of making another database lookup.

 In the real world, I am using this to pull through a full size image for a
 Schema Json-LD object.

 I've also used it in the past as part of function to filter the img src to
 replace it with the smaller img of the same ratios, for a front end
 javascript function to dynamically calculate the correct srcset img to get
 based on image width on-screen.

 Again, not elegant, but works.
