In reply to Flinticus:
I've got the Boardman Tasker omnibus. There are a few photos from the climbs up Dunagiri, Changabang and K2 although the photos themselves are shown from page 20 in the following book, the Shining Mountain. Dick Renshaw is credited with the Dunagiri photos and Joe Tasker has the credits for 3 of the Changabang photos and Pete Boardman the other 5. Joe Tasker has the credits for the 2 photos from the K2 expedition. One of them is the photo of the snow slope that avalanched killing Nick Estcourt and very nearly claiming the life of Doug Scott were it not for the rope snapping.
