It seems difficult to find photos of Norwegian steam in regular service. http://www.njk.no/ has a rather limited gallery. Flickr is lacking, as far as I've seen. I once found a gallery on fotopic.net with Norwegian steam in 1969-70, some retired and some working. I've never been able to relocate it. That's exactly the time period I'm looking for. http://www.railfaneurope.net/pix/no/steam/pix.html has nothing. http://www.jernbane.net/db/kat.asp?ID=7 and http://www.jernbane.net/norge/damp/ have some, but again, most are museum pictures, or else very old. Photos also aren't much use to me without time and place, as most at that site are. I can't read Norwegian, so I expect there are sites out there I can't find.
Fan of late and early Conrail... also transition-era PRR, 70s Santa Fe, BN and SP, 70s-80s eastern CN, pre-merger-era UP, heavy electric operations in general, dieselized narrow gauge, modern EFVM and Brazilian railroads in general, transition-era DB and DR... why bother trying to list them all?
