-auto-orient is working incorrectly with thumbnails

[finrist]

We have images (jpg) whose thumbnail in the EXIF has "Orientation: 6" but the actual image has not. But when we convert it with "-auto-orient" it rotates the image 90 degrees even though only the thumbnail is said to be rotated.

The image looks good in every program I've tested, GIMP, Photoshop, Windows own, Mac OS X own, etc.

-thumbnail will strip the profile containing photo orientation image that -auto-orient needs. -auto-orient can not work when it does not have information to work with!

You MUST apply -auto-orient BEFORE -thumbnail.

Alternative use -resize, then -auto-orient, then -strip

If you mean the thumbnails within JPEG. They are not currently handled by IM. More typically they are removed with either -strip or -thumbnail as part of processing, or re-created after processing.

Yes, it is the thumbnail within the JPEG that is not working. This thumbnail has "Orientation: 6" attached to it, but when i use -auto-orient IM applies this orientation to the real image, not only the thumbnail.
