To rotate an image, open the file’s menu and choose Rotate Right. Both rotation options are available on the image viewer menu if you open the image first. Images in the Photo Library need to be copied elsewhere before rotation.
Select multiple images to rotate at once by using a Custom Task. Choose Create Task from the actions menu. See our guide here.
This is a Premium Feature and requires FileBrowser Professional. Click the App Store link and purchase the FileBrowser Professional bundle at a discounted cost, by only paying the difference.
