If you've taken photos with an iPhone / iPad's default camera app, while the device is not correctly oriented, the photos will be upside down.
When taking a photo, ensure that the Home Button is closest to your right hand, and the rear camera is closest to your left hand / ceiling.
If your device is not correctly oriented, the photos may display properly on your device but when emailed, uploaded, or viewed in some browsers they will display upside-down. This is due to how Apple applications take and save photos.
Edit and Rotate
Most apps will contain built-in Edit modes that allow for quick and easy image rotation. If you notice that your image is upside down when uploaded to LotWorks, please edit the image on your device, and try the upload again.
