But is the “undue” stress of a taught wire actually a problem for typical weights?
True story... I once went to a public museum in Malaysia to photograph a painting I had an interest in. The light was bouncing off the glass, so I raised its lower edge by placing a cigarette packet behind the frame. Worked a charm and I got the photo I wanted, all without the guards seeing. I came back a year later and later lo and behold the cigarette packet was still there.

A professionally hung painting would not be on wires but on a dedicated wall mount. But Cable mounts are easy to reposition. True story...

This sentence is very funny to me: "Most people in the Northern Hemisphere hang their pictures on a wall." I guess OP did some research but perhaps wasn't exhaustive and didn't want to generalise to below the equator. People write funny and quirky things. I'm glad things like archive.org exist to save the quirkiness for future generations.
Anne looked, then answered, "It's white on this side."
Yes, in this case, it's quirky and possibly endearing. When people feel like they need to document trivial comments by writing "Edit: typo", less so.

Do you know where I could find a free body diagram for a door with hinges? I don't understand why my doors are trying to close themselves. I think something is not level, but I don't understand the hinges though to draw a diagram myself.

In an ideal situation everything is level in all directions.

try a polarizer next time. https://en.m.wikipedia.org/wiki/Polarizer https://en.m.wikipedia.org/wiki/Polarizing_filter_(photograp...
My money would (at least partially) be on the guy having bought a duff hanging system, or had it poorly installed. I've just returned from a holiday where I visited a few art museums. They all had hanging systems. None of them had frames tilting as excessively as the one in the photo on this guys blog. In fact, the tilt was barely perceptible (if it was there at all). I'm sure he's making a perfectly valid point in t…
Here's a random photo of Louvre, place with both the art nerds and money to hang things "properly". You can clearly see they tilt forward on the cables, maybe not as much as OP but still.
Earlier quoted context omitted.

They auto-close when the top hinge is more to the outside then than the bottom hing, or the whole frame is tilted towards the inside (where the door does not swing into). You can try adjusting the hinges with a tool. In an ideal situation everything is level in all directions.
Not sure if this is any clearer, but the door will close itself if the bottom hinge is offset from the top in the direction the door opens. Picture the angle of the bottom of the door when it is open 90 degrees and it might be easier to visualize why it falls shut.
