I don't know about those particular photos, but in _The Eighth Day of
Creation_ (Expanded Edition, reprinted by Cold Spring Harbor Press,
1996) by Horace F. Judson, on p. 78 it describes Franklin's colleague
Wilkins learning to extract DNA from calf thymus.

It's definitely worth a read if you like history of biology.
