Scott, let us summarize the evidence again for the two photographs taken secretely in Auschwitz in summer 1944:

Number 2:

Evidence:
A note from the Auschwitz resistance dated 4th Sempember 1944 stating that the photographs show a place were the people had to undress before they were sent into gas and a place were the dead corpses were cremated in the outside because the crematoria could not cremate all corpses.
The testimony of David Szmulewski, a prisoner who claim that he was present during the operation, stating that the photographs were taken taken near crematorium V and show extermination of people.
The examination of the photographs by the Auschwitz expert Jean-Claude Pressac. He has identified that the photgraph number 2 was taken from the gas-chamber and photograph number 1 from the yard of crematorium V.
A letter written by Jewish woman from Hungary about her experiences in Auschwitz-Birkenau found in a dossier of Raul Wallenberg. The letter is quoted in Gerlach, Aly: Das letzte Kapitel, page 287. The authors consider that the letter is authentic since it mentions details that are confirmed by recently found documents. The letter describes presicely the scene established by Pressac based on his examination of the photos and Szmulewksi's testimony. An extract:
"Wir gingen weiter. Nach einer viertel Stunde kamen wir zu einem kleinen schütteren Wald. Auf einem freien Platz mußten wir uns setzen. Es wurde uns wiederholt gesagt, daß wir gebadet werden, dann bekommen wir alles was wir brauchen. Ein Teil unserer Gruppe wurde gleich etwas weiter geführt. Sie mußten sich auskleiden und wurden nackt baden geführt. Kurz hierauf sahen wir in einer Entfernung eine sich in der Länge ausbreitende hohe Flamme."
Numerous testimonies that confirm that the Jews unfit for labour had to undress in the wood, were sent into the gas-chambers of the crematoria or the Bunker and were cremated in burning pits.
Question: Where does the evidence leads us?
Consider the following: We have a photo from Dresden showing mass cremation and the following evidence:
We have the testimony of the guy who took this photo saying that it shows cremation of people at the Altmarkt who died during the bombing. We have a wartime letter from the Ordnungspolizei saying that bombing victims are cremated at the Altmarkt. We have an export opinion stating that the photograph does show the Altmarkt in Dresden. We have numerous testimonies stating that many people died during a bombing and were cremated in the open air.
Where would the evidence leads us?

By the way, we know that about 300.000 Hungarian Jews who were not fit for labour were deported to Auschwitz and yet - assuming that Holocaust deniers are right - there is no evidence what happened to them in Auschwitz and WHY there were sent to Birkenau, an alleged labour camp!
Here is the question for you: What do you think has Höss likely done with 300.000 Hungarian Jews in his camp who were unable for work? Here is what Höß told Martin Gilbert what he has usually done with Jews that were not able to work:
-Höss wrote:On the average about twenty-five per cent were found to be fit for work. These were marched off immediately into the camp, in order to change their clothes and be received there. All the luggage remained on the ramp and, after those unfit for work had also been sent off, it was brought to the store of personal effects, to be sorted out. Those unfit for work were classified according to sex - men, women and children - and marched off to the nearest available extermination installation. Those unable to walk and women with small children were transported there on trucks.
When they arrived, all of them had to strip naked in rooms which gave the impression of being delousing installations. The permanent labour unit of prisoners who worked in these installations - and who were also housed there and did not come into contact with other inmates of the camp - helped with the undressing and coaxed the hesitant to hurry up, so that the others would not have to wait so long.
[..]
The moment the entire transport had entered the chamber, the door was closed, and simultaneously the gas was forced in from above through a special aperture. It was Zyklon `B' gas.......
If you add the two photographs and the drawings of the Sonderkommando Olere to the photographs from the Auschwitz Album (that was made during the Hungarian Operation), the complete picture of what happened in Auschwitz Birkenau with the transports from Hungary and the ghetto Lodz emerges.
Remember that the Auschwitz Album shows the arrival of one or more Jewish transports from Hungary and the selction at the ramp into fit and unfit people,

At least two different groups of unfit Jews can be identified at the photographs.
One group of unfit Jews was not sent to the big crematoria. They had to march through the camp,

most likely to the wooden area at the edge of Birkenau:

Yad Vashem has identified the area, it is near crematorium IV.
They had to undress and to walk towards the gas-chambers.

They were killed with Zyklon-B.

The doors were opened, the corpses were dragged out some meters behind the crematorium, to a burning pit:

Note that the author of the Auschwitz Album has made also a chapter called "Nach der Entlausung", after the delousing. He took 10 pictures. None show Jews unfit for work. Were they not deloused? Further, he has another chapter about the fit Jews, "Einweisung ins Arbeitslager", registration in the labour camp. He has no chapter saying anything about the fate of the unfit Jews.
Doesn't this, and the fact that the groups of unfit Jews were all directed to the crematoria (which have been identified as killing facilities in numerous eyewitness accounts) alone strongly speaks for the thesis that the Jews who were not fit for work were killed in Auschwitz?
