In this thread, Wyatt repeatedly insults people who aren't as easily convinced as he is of alleged gassings at Auschwitz by posting these photographs which, according to him "prove" there were introduction holes into the alleged gas chambers!
These photos have been discussed at length by revisionists and do not at all support the conclusion made by Wyatt.
All of the believer Holocaust historians ignore essential elements of these photographs in order to justify the conclusions that these objects are Zyklon B introduction columns, which they cannot be.

Rudolf shows that these objects in the train photograph cannot possibly be Zyklon B introduction holes. He states:
If these objects are really Zyklon-B-introduction shafts, as Pressac believes, then one must assume that the objects are:
a) of equal size
b) regularly aligned
c) evenly distributed along the roof
d) nearly the same color and
e) casting approximately the same shadows.
Figure 77 points out the outlines of the cellar, indicating its breadth as well as the approximate width of the three objects. Despite the mediocre resolution of the photograph, it may be concluded that these objects are of differing widths, not evenly distributed over the roof, but stand, on the contrary, close together.
It also seems peculiar that the shady side of the first object seen from the left, compared with those of the other two objects, is remarkably light in color. Figure 79 shows the alignment of perspective, viewed from above, on which these objects can possibly be located (Boisdefeu 1994, p. 168). As none of the requirements set forth above is met, the argument that these objects are above roof parts of Zyklon-B-introduction shafts must be rejected.

And we have photographs of the same roof from January 20, 1943 and Summer 1943, which show no holes, no columns, nothing whatsoever:

We also know (as you can see in the above photograph) that there was construction work being done at the time. Seeing as this is the case, it's only too likely that the space on the alleged "gas chamber" was being used to place materials, which is why in February 1943 we see some misshapen objects on the roof.
It will therefore be necessary to find another explanation for the objects in the photograph taken in February 1943, such as, for example, that some sort of objects had been placed on the roof – perhaps in the course of constructing the building, undertakings which were obviously still underway – or less likely that the picture has been retouched at a later date.
So what were these holes? Probably, as David Irving and Mattogno agree, tar or bitumen (a binding agent) used for insulation of the roof, as you can see being built in the photograph from January 1943.
