When you first try to either take an image with your camera or choose an image from your library you should be prompted by an alert to allow Insite to have access to them. If you did not allow access, then you may not be able to use these features so you can change your settings by doing the following:
To change your permissions on iOS

2. Go to Privacy.
3. Choose either Photos or Camera depending on which area you would like to change the settings for.
4. Look for Insite in the list and change the settings to allow or disallow access depending upon your preferences.
