+### Does this problem relate to file caching?
+
+The default behaviour of libvips is to cache input files, which can lead to `EBUSY` or `EPERM` errors on Windows.
+Use [`sharp.cache(false)`](https://sharp.pixelplumbing.com/api-utility#cache) to switch this feature off.
+
+- [ ] Adding `sharp.cache(false)` does not fix this problem.
+
+### Does this problem relate to images appearing to have been rotated by 90 degrees?
+
+Images that contain EXIF Orientation metadata are not auto-oriented. By default, EXIF metadata is removed.
+
+- To auto-orient pixel values use the parameter-less [`rotate()`](https://sharp.pixelplumbing.com/api-operation#rotate) operation.
+- To retain EXIF Orientation use [`keepExif()`](https://sharp.pixelplumbing.com/api-output#keepexif).
+
+- [ ] Using `rotate()` or `keepExif()` does not fix this problem.
