+The `width` and `height` fields already account for orientation. For example, if the image has a width of `4000`, a height of `3000`, and an orientation of `6` (which means the image should be rotated 90 degrees clockwise), imgproxy will return `"width": 3000` and `"height": 4000`.
+
+The `orientation` field contains the EXIF orientation value (from `1` to `8`). If the image doesn't have EXIF orientation data, imgproxy will return `1`.
