Two pictures look the same.Now I want change the picture size.
Use command :
convert [picture name] -auto-orient -thumbnail 400x /tmp/imgmogr2-226590685.jpeg.
I found two results is different.

I think the correct link is http://needkane.qiniudn.com/error6.jpg.

It looks like a bug to me (tested with v6.9.0-2). The Exif thumbnail image has an Orientation tag, and I'm guessing that the -auto-orient routine wrongly thinks that tag applies to the main image.
