First, Christopher, you asked about the origin of the photo itself. It was taken by Sam Hollenshead:
In 2001, Sam Hollenshead was a staff photographer for Labor Research Associates.
For example, if you search the articles from the union site workinglife.org, you will find a lot of examples of his work.

Sam Hollenshead worked as a photographer from 2001-2003 documenting union labor throughout NYC. In 2004 his photographs of the rebuilding of subway infrastructure at the World Trade Center site were exhibited at the Museum of the City of New York.

After 9/11, he documented workers at the World Trade Center site clearing debris and rebuilding damaged subway lines. Images from this project were published in the New York Times Magazine and displayed at the Museum of the City of New York in a group show with Magnum photographer, Bruce Davidson and MacArthur fellowship recipient, Camillo Jose Vergara. A solo exhibition of his subway photographs is currently on display at the New York City Transit Museum until December 2006.

When historians sit down to write about September 11th and its aftermath, they will have to reserve a page of History for the workers at ground zero whose tireless efforts saved lives and helped New York City rebuild itself. Here is the story of workers at ground zero. Photography by Sam Hollenshead.
Here is the sequence of photos taken by Mr. Hollenshead showing steelworkers engaged in the cleanup. Please not the presence of your favorite photo in the sequence:
Hollenshead was there to document the efforts of union steelworkers. That's what he was doing for a living at the time. That's why, if you know anything about the photographer and why the picture was taken, that it was relevant to all of the other pictures Mr. Hollenshead took of guys with torches cutting stuff.
I wrote to Mr. Hollenshead about that picture specifically, and he said:
"i do recall that the photo of the firefighters was taken almost a month after 9/11 and the cut beam in the background was almost certainly cut by a worker, not the result of 'intentional demolition.'"
That's why it has the date that you asked about.
Gage and Jones still use this photograph as evidence of CD, and their lack of investigation into it is, to me, convincing evidence of their intellectual bankruptcy.
In order to have slag run down the outside of the box, the cutter would have to be inside the box
So, how do you suppose someone put thermite inside of a box beam, to make that happen.
But, in fact, yes, you do want to cut a box beam from the inside out. You do this by making a hole large enough to get an angle-tipped torch in there.
Why? So, you can be sure you are cutting all of the way through.
If you take a look at the box column with the strap on it, discussed above, you can see that there is a large hole in the facing side. Waddya suppose that hole is for?
