----------------------------+-----------------------------
 When uploading rotated images that contain EXIF orientation data wordpress
 rotates them even though they're already rotated. I worked out that you
 can prevent this using the following code but it doesn't affect the
 thumbnail images, and they're still rotated.


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


 I tried updating the metadata, but it didn't work to prevent the rotation
 of the thumbnail images.


 {{{
 function prevent_thumbnail_rotation($metadata, $attachment_id) {
   $metadata['image_meta']['orientation'] = '';
   return $metadata;
 }

 add_filter('wp_update_attachment_metadata', 'prevent_thumbnail_rotation',
 10, 2);
 }}}

 The images are all rotated correctly before upload.

 After upload many have '-rotated' appending to the file name, if the above
 code isn't used. This I want to avoid, as the images are to be attached
 via csv import and each image filename will need to be manually edited if
 it was rotated. The import fails if the image is rotated, even though the
 actual file exists, it's probably not part of the attachment post.
