When uploading 8 pictures via Media, Add New, I get this error:

    Post-processing of the image failed. If this is a photo or
 a large image, please scale it down to 2500 pixels and upload it again.

The images are about 400KB to 700KB, so are not huge. Those images are processed via Postie, but also fail with the above message when I manually add the images via Media, Add New. Other images with the same dimensions (3888 x 5184px approx) upload and process normally. I also tried to upload the 'problem' image files singly, but the same error.

I have increased the max_upload_size to 128MB, and the max_post_time to 300, but no fix.

Some research seems to indicate that it's a problem with the large image processor added to 5.3, and say to add this line to the functions.php file to disable it.

add_filter( 'big_image_size_threshold', '__return_false' );

So I did that, then tried to upload the same 8 files again via Media, Add New, but still get the failure on the same two files.

There is some discussion about this new feature here: / .

Has anyone else experienced this issue? Any solutions?
