Importing Photographs from Camera Roll
PostureScreen can use photos that were not taken directly through the application itself.
All you need to do is get that photographs on to your iPhone or iPad. There are countless ways to do this. You can sync the photos, use email and save the images, or use DropBox, Box, iCloud, Apple’s PhotoStream, etc.
If you would like to shut off the camera and use photographs already on your device that you were emailed or taken with the camera on the device outside the application, the following tutorials will demonstrate this process.
NOTE: If your device is Augmented Reality Capable and you have this feature turned on, you must TURN OFF Augmented Reality in order to enable importing photos from the camera roll.
