Good evening, Rick & Wings,
Almost all the larger scans are linked from David Johnson's terrific compendium (newly updated) at:
http://pilots-n-planes-ww1.com/index.htm
Others from here and there around the Web, since I don't have a site of my own.
Many of the images can also be found in Squadron and Albatros publications. For example, the Kesta 4 image can be found in the latter's Fokker D.I-IV Datafile. The caption in that publication does not name the unit's personnel, but I would put money down that other Forum members can name each and every one. Dan-San, are you listening?
Best,
Stefen
