 Replying to [comment:4 desrosj]:
 > The `2048x2048` and `1536x1536` are new sizes introduced in [46066] in
 an effort to enhance the way WordPress displays images on the front-end on
 larger, high-density devices. They make it possible to generate more
 suitable `srcset` and `sizes` attributes, and not use the original, often
 non-optimized image.
 >
 > These new sizes will be generated for all newly uploaded images going
 forward.
 >
 > I am seeing the original image in the meta data that you supplied in the
 `original_image` index, so it seems to be working as intended.
 >
 > - The original image is larger than the new big image threshold used to
 cap images at an upper size limit.
 > - The original is scaled down to be more useful using the two new image
 sizes.
 > - The original is preserved in the attachment's meta data.
 >
 > If you wish to disable this big image threshold (or tweak it to your
 liking), you can use the `big_image_size_threshold` filter to return a new
 size. Returning `false` will disable this.
 >
 > I'm goign to close this out because it appears to be working as
 intended. If I am misinterpreting the questions, or you have more, feel
 free to reopen to discuss more.


 Hi, Did I misunderstand? You say returning false will disable this. I
 tried using this code and it has no effect.


 {{{
 add_filter( 'big_image_size_threshold', '__return_false' );
 }}}


 Serious issue for me, I'm allowing users to upload images but have been
 overwriting the full size uploads with thumbnails. For legal reasons I
 don't want to allow large images of user uploads just in case of copyright
 issues. And I just now noticed multiple unregistered very large images are
 being stored on my server! I must disable these sizes.

 I see these being created -2048x2048.jpeg, -1536x1536.jpeg plus I've also
 seen some files appended with -scaled.jpeg - I need all of these removed.
