When you import images into Fundy Designer®, the orientation of the image is determined by the metadata embedded in the original image file. This usually only happens if you import your images straight from your camera into Fundy Designer.
If the orientation is incorrect once imported into Fundy Designer, you can re-process images through an image processor such as Bridge or Lightroom. This will generally correct the issue.
