When you take photos on your phone while holding the phone vertically, they may come out sideways when you upload them to CompassNet despite looking normal on your computer. We highly suggest taking photos with your phone held horizontally as that will avoid the issue. 

If you already have photos taken vertically, you can open the pictures in preview and just rotate the image left or right, then back again. This will fix the data in the picture that tells CompassNet which way to display it.
