Meant to update on this earlier. I did clarify and they meant photos of the map so they could enlarge them and see it without having to put their glasses on. I would say this is ok even though it is using an electronic device to aid navigation. I'm still unsure whether using photos of landmarks would be ok or not. The current wording seems to allow it though:

“If a race is classified ‘non-GPS’ (NG) then the use of any electronic device to delineate a route, to display current position on a map, or as a compass, will be prohibited."
