Photos with surface problems don't scan well. You need to copy the
picture with a camera using the standard lighting setup. This is
two lights at about 45 degrees to the surface so there are no
visible reflections. In really bad cases you need to put polarizers
over the lights and a polarizer over the camera lens to eliminate
the reflections.
A search on copying or a visit to a library or book store will show
you all the details.
