When adding Photos to any section of WorkPal (e.g. Jobs, Forms etc), there are two options.
On iOS Devices, tapping the "Add" button will show two options "Take New" and "Select From Photo Library".
On Android Devices, when tapping the "Add" button, this will bring you to the camera viewfinder to take a new Photo, while pressing and holding the "Add" button will bring you to the Camera Roll to select a previously taken Photo.
