Recently my uploaded image files are rotated unexpectedly.
Then I fixed by referring this web site.
– Japanese geek
The point is to use EXIF information in image file.
[WordPress] スマホで縦向き撮影した写真が勝手に横向く(回転する)問題 | IT女子のお気に入りフォルダ
スマホで縦向きに撮影した写真(JPEG画像)をWordPressにアップロードしたら、勝手に回転して横向きにな
This is source code added in functions.php.
Point is from switch ($orientation) parts.
– I just referred above site sample…
function rotate_uploaded_image_file($file) { if ($file['type'] == 'image/jpeg') { $image = wp_get_image_editor($file['file']); if (!is_wp_error($image)) { $exif = exif_read_data($file['file']); $orientation = $exif['Orientation']; if (!empty($orientation)) { switch ($orientation) { case 8: $image->rotate(90); break; case 3: $image->rotate(180); break; case 6: $image->rotate(-90); break; } } $image->save($file['file']); } } return $file; } add_action('wp_handle_upload', 'rotate_uploaded_image_file');
FYI
This is official API guide of PHP.
PHP: exif_read_data - Manual
And we need exif extension to use exif_read_data().
Please visit my git commit for more detail.

In some internet site there is plugin to resolve this problem.
But in my environment it didn’t resolve.
