http://custom.simplemachines.org/mods/index.php?mod=4087IntroductionThis mod allows the automatic rotation and/or flipping of images ONLY IF the EXIF information contained within (if such exists) indicates that such processing is required in order to show the picture upright.
NOTE: SMF contains an option called Re-encode potentially dangerous image attachments, which is turned on by default. This re-encoding removes the orientation information from attachments (amongst other things), which means that attachments uploaded prior to this mod being installed will NOT be able to rotated properly, as the EXIF information is missing from the re-encoded attachment file!
Admin ChangesIn Admin => Forum => Attachments and Avatars:
o Browse Files: There is a new column for image rotation. Note that this column isn't shown when there are no images in the list.
o File Maintenance: There is a new section with a button to clear the orientation flags in the database.
