Reminds me of the Uruguayan Air Force Flight 571 documentary I watched last night. I googled out of interest as to why the bodies are left where they lay, found this:
Generally if another climber takes a picture of a dead climber, they keep it to themselves. Climbers are much like soldiers, they have a deep respect for their own kind. Everest is a bit different though, as a lot of the people who attempt it these days are not really Climbers, but people who pay real climbers to guide them to the top. Much like if the Soldier of Fortune reading mall cop got to spend six months on the front lines in Iraq.
Also, time is of the essence on a summit push, and it is Really Fucking Cold, so stopping to remove your mitten liners, pull out your camera and snap a photo takes time and effort. Just doing something like that at that altitude can be exhausting in itself.
They do exist though. Look around at coffee table books of Everest, especially ones compiled by non-climbers. I think the Newsweek or Time issues from 1996 or whenever that Really Bad Day happened ,when Rob Hall and Scot Fisher died and Beck Weathers pulled a Jesus, showed a body or two.
As others have said, it's just about impossible for a healthy climber to bring a body back from up high on Everest, especially since there's really no such thing as a healthy climber at that altitude.
It's not just Everest, pretty much every big mountain has a body or two somewhere up high. Even "small" mountains like Rainier have bodies hidden in the snow, though that's more a matter of not being able to find them. They pop out of the glacier every now and then and the rangers or guides recover them.
Thought it was interesting.
