Support "Orientation" EXIF tag

[Aleksej]

The tag specifies that the image is to be displayed rotated and how.

The tag is supported by:

• MediaWiki (it generates thumbnails already rotated).
• digiKam (there is an option to set Orientation after rotating an image)
• Geeqie (rotates for displaying)
• Nautilus
• Eye of GNOME
• Thunar
• exiftran (according to the man page)

If it's supported by that much, agreed we should support it too!

Should also the original image be rotated? Or should it be kept untouched? If untouched, can we rotate it by HTML/CSS ?

The file should be kept untouched (that's the point of still using the tag and not just rotating the image, because rotation can be lossy).

Do any browsers support that tag though? Might be a bit annoying if you click on the image and it brings you to an un-rotated version?

Conversations on IRC seemed to indicate that only Konqueror supports it right now? Am I wrong?

You can provide a converted file, but also provide the original file as "Original".

I wonder if that is something to consider. It doesn't seem to me that many people view the full size image by itself in a browser. That is just me watching people use Gallery and Flickr. YMMV.

I am for leaving the image untouched, letting the metadata dictate how it it oriented, and then let people use their native OS/apps to manipulate the "raw" image if they choose to save it for whatever reason.

I was going to make a feature request that covered this, but the idea is that I like the way Flickr has multiple sized images, with a sizing menu above it. I get the impression they do it that way to obfuscate how to download images, but I think it would be nice to produce a view like that in a non-creepy fashion.

Check out https://secure.flickr.com/photos/goldengatexpress/6282214635/sizes/l/in/photostream/ for an example of the sizes and the creepy, "let's pretend we don't know how websites work" message.

Question: Will this work in a way that is retroactive? I've begun modifying my images to orient them correctly, but if this will load it at view time or something, I wouldn't have to do that. How lazy can I be? =]

There was a recent change to the way Wikimedia Commons handled EXIF orientation data. See: https://secure.wikimedia.org/wikipedia/commons/wiki/Commons:Rotation

That's what I meant by support in MediaWiki. As you can see, the change is still controversial there, but it's mainly because of existing files with wrong metadata.
