 Error message:
 ''Post-processing of the image failed likely because the server is busy or
 does not have enough resources. Uploading a smaller image may help.
 Suggested maximum size is 2500 pixels.''

 ajax error content:
   Fatal error:  Uncaught TypeError: round(): Argument #1 ($num) must be of
 type int|float,
   string given in C:\***\wp-admin\includes\image.php:844

 line 844:
 {{{
 $meta['aperture'] = round( wp_exif_frac2dec( $exif['FNumber'] ), 2 );
 }}}

 Images with a meta > camera > aperture of 0 seem to cause this error.
 An aperture value of 0 can occur if the camera is using a manual lens with
 no connector pins, for example an adapted vintage lens.
