Preserve the source
Keep the original unchanged. Rotate a duplicate using a trusted local editor, then save or export it so the visible orientation is correct. Avoid a screenshot unless ordinary export is unavailable.
Check the resulting image
- Open the exported copy locally.
- Confirm the subject and framing are unchanged.
- Check size and supported format.
- Upload the corrected copy once.
A portrait that looks upright in your photo library may appear sideways in an upload preview. The preview is a useful check of what the service will receive, not a reason to rotate the original repeatedly.
Distinguish rotation from mirroring
Turning an image upright is different from flipping left and right. Keep a note of the actual transformation used. If corrected orientation still produces no result, that does not establish an upload failure; the service may simply lack a relevant indexed source.
