Steve,
That image was a scan from Adam R. Johnson's book "Partisan Rangers of the Confederate States Army." Some of the corrections I sent didn't make it into the book's initial printing - I don't think that image was taken in camp - I think it was taken at some POW camp after the Ohio Raid, as there are several other identifiable officers from Morgan's units in this image, but not members of the 10th Ky. Cav.
