I've read several posts about this. Essentially, someone posts a picture from their phone and when the attachment is accessed, its sideways. Apparently the thumbnail that the iDevice creates is oriented correctly, but the image itself isn't. I suspect that data is stored in EXIF data somewhere.
It's also my understanding that this has been handled in at least one gallery product, but I'm not positive of that. I've read that its not broken and won't be fixed. I've read its non-trivial. I've read that simply because ipboard and vBulletin have a feature isn't justification enough for it to be implemented in smf.
I'm hemorrhaging users who are becoming accustomed to Facebook handling the resizing
and auto-rotating of images with the click of the upload/post button. Turns out, the only other major forum whose niche my forum shares also manages to handle both these issues with aplumb.
Could anyone point me to where those changes would need to be made if this can't be dealt with officially?
