How does the auto-rotate option work?
It is recommended that you leave auto-rotate enabled, since it will only rotate images as needed and will not rotate photos that don’t need it. Auto-rotate works by examining the image’s metadata – many photos taken with digital cameras contain orientation metadata that indicates whether the image was taken with the camera tilted. These photos may look correct in the finder, but if you view them in a web browser, they’ll be rotated incorrectly. EasyBatch’s auto-rotate option corrects this problem by rotating the actual image data so it appears correct regardless of where it is viewed.
