Aurigma Upload Suite 8.0.67
ImageUploaderFlash..::.EnableAutoRotation Property HTML5/Flash Uploader ASP.NET
Gets or sets a value indicating whether the automatic EXIF-based photo rotation feature is enabled.
Assembly: Aurigma.ImageUploaderFlash (in Aurigma.ImageUploaderFlash.dll)
This feature works only for those photos which store EXIF information and when orientation details are written there. Keep in mind that not every camera can recognize orientation properly, and therefore HTML5/Flash Uploader will not rotate it.
