I have some pics taken with my iPhone. When I move them over to my PC, the appear with correct image rotation alignment; but when I post them online, they appear out of alignment by 90 degrees.
I opened FastStone Image Viewer and see the images correctly aligned, but they still appeared wrong when posted.
I have read that metadata in the file contains image orientation information. Is there a way to access and change that information using an app? I tried with EXIF and failed miserably.
