Naturally your setup is set for LANDSCAPE view, so all you need to do is spin each image that goes into the project so that the top is actually on the right. It’ll make you sick to tilt your head while editing a long project, so I would use an extra monitor that you can tilt during this edit process. My project was a simple slideshow, so all I had to do was pan my images left to right (or in the tilted case TOP TO BOTTOM).
