reopened. Please see here:
https://commons.wikimedia.org/wiki/Commons:Village_pump#Autorotation_using_EXIF_tag_with_MW_1.18

Firefox 3.6 and Opera 11.5 do not rotate images based on EXIF tags: totally
confusing when you click on the 800px preview to see the image in full that the
image is suddenly wrongly rotated by 90° (portrait image). Usability failure in
my opinion. Next time: Please ask Commons community before! :-)

Solutions(?): 
*rotate them serverside (lossless!) and offer an additional download link
(ugly) for the original image. 
*Get the browsers to rotate images based on EXIF.

EXIF rotation is a confusing idea ;)

And: we will get thousands of images being wrongly rotated in our old images!
Images have wrong EXIF tags but it didn't matter since MW did not respect them.
We probably need a bot deleting the wrong tag to fix them: 

exiftool -Orientation= filename.jpg
