Whether this can/should be changed is a subject to discussion, though.

I propose LJ should, on upload, examine images for whether their EXIF orientation matches their present orientation, and then where they don't, by default, generate a rotated version of the pix for serving when called, and serve that instead; and in Scrapbook, with the rest of a picture's properties, there should be a ticky box for controlling that. By default for all pix (going forward) "Correct rotation" should be selected; it should be greyed out where an image's orientation matches that specified in its EXIF; in this way, if somebody doesn't want their EXIF honored on a picture, they can turn it off ( ... )

It is not much of a technical problem to have an (opt-out) option to serve rotated images, but I can't see a way to implement it without cluttering the UI. Having the 'original' original image available at 'xxxx_verbatim.jpg' and unavailable through the drop-down menus seems to be a better solution to me, assuming that we care that much about both preserving the original content and showing that content rotated by default.
I guess I will need to think about the issue a bit more and discuss it with the colleagues, heh.

I doubt anyone cares about original images much though because no one really needs to see them on a 72dpi monitor.
Hmm. I don't know that we can make the assumption that the only purpose of posting an image to LJ is to display it on a screen. Scrapbook is a repository that has permissions synced to one's LJ; as such, I bet someone, somewhere is using it as a distribution system for higher resolution image files to custom friends lists. Maybe chat up some of the photography comms, see if this would be an issue for them?
(Which suggests a Meta-Suggestion: I'd love to see LJ-as-an-institution actively solicit feedback from relevant comms in situations like this, instead of just hoping some of them are haunting Suggestions. For something that might impact how images are handled, why not search out the three biggest, most active photography and fan art groups, and post something that either brings the issue to them where they are, or invites them into a discussion here or on lj_dev. I'm not ( ... )
