Photos and documents
Photos
+ Photo opens the device camera. Take the picture and it is added as a Photo row.
Documents
+ Document opens the document scanner. Point it at the paper; it finds the edges by itself and lets you correct the crop before it saves. The result is added as a Document row.
tip
Use + Document for a prescription or another form on paper. It gives a straight, cropped image, which a plain photo does not.
Both are stored on the device as images and go along when you upload. The eye button on the row opens the picture.
