An UPDATE: After further testing, it does appear that there is some change in the file size when you use Windows Photo Viewer to rotate the image. We recommend using Adobe Photoshop instead, as there is no change in the file size.
It can happen to anyone: inevitably, images are scanned and uploaded into your repository upside down or sideways.
It can be a pain to delete and load them again into your repository. While you can’t rotate images within Islandora, you can follow the simple steps in this document to fix scan errors within your repository. Essentially, instead of deleting the image, you will be replacing it.
