Did he really print photographic images, directly transferred to his printing press? In that case, he was way ahead of his time. Actually, way ahead of photography!

Photographic etching: the plate was covered in a photosensitised resist which was exposed to the negative, then etch the plate with acid to leave a printable image.

When was this technology established? Is this what was used by newspapers in the 1800s?
One practical question: How were these etched metal plates integrated with the rest of the printing process? Would you have to pass the newspaper pages through two distinct printing cycles, one for printing the text, set in lead type, and then a second one, for the etched photographs? Or was there some way to combine them to a single print cycle?

if I recall correctly, it was in the early 1800's by Nicéphore Niépce[^] and the plate was attached to a wooden block which was then typeset with the (mostly lead) characters which formed the text, a spectacularly tedious job that I did far too often at school as the head of the Printing Society. Loads of little letters, loads of little wooden wedges to hold them all in place and loads of swearing when the ![Elephant | [mastadon]](https://www.codeproject.com/script/Forums/Images/elephant.gif) ing wedges fell out followed by all the letters ...

The resulting Form (yes, really) was then run over by an ink-laden roller followed by pressing it onto a sheet of paper - which gave rise to the phrase "stop the presses!" for breaking news.

And this was the technology used by local newspapers in the mid-1800s, right?

The only time you used multiple passes was when you wanted actual colour: four passes, four colours: CMYK
But that came a lot later, newspapers were black and white (and messed your hands up which is why gentlemen wore gloves to red The Times) for a long time.
Registration was a bitch: getting all four colours to line up on the paper was no fun at all!

Last time I saw a professional typesetting system (a few years ago, not many!) it still had the option to add registration marks outside the printed area for multi-pass alignment. I believe that modern printing presses have automated functions for doing the alignment.
The precision required for aligning a grayscale graphical image in a rectangular area left by the text printing process allows a magnitude (or more) freedom. A millimeter or two won't matter. So if they wanted to do a two-pass printing of first the text, then the photos, I am sure they could. But did they do that? (Precision requirements for printing color photos does not prove that the answer is 'No!')

Probably not: it would have required two forms created (labour intensive work by skilled craftsmen!) then either two presses or "press them all" then change the form and press them all again. That's a lot of work so it's unlikely to happen if a single pass will do it. Whatever is cheaper to produce will probably be used, especially as there was a lot of competition (and taxation!) with newspapers in those days.

Trying to get just 2 colors to line up correctly in a block print in my HS art class was bad enough. 
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

Google "digital offset printing newspaper history" - 86 million hits.'
Google "computer to plate" - 129 million hits.
How far down in those hit lists do I have to go to get information about how (and when) technology in the mid-1800s allowed photos to be transferred to the newspaper printing presses of the day?
I am sure that you haven't tried. I can assure you: After 200+ hits, you still don't have a clue.

At what (approximate) time did newspapers get technology letting them transfer a photograph (or for that sake, any flat image such as a painting) to a press more or less "automatically", in the sense that there was no need for a graphic worker / artist to copy the image by hand to some traditional technology such as lithography?
You implied that you were looking for the time graphics were able to be passed to the press fairly automatically. The process Griff pointed out is not automatic - it was very labor intensive, as he said. It wasn't until the digital age that such processes came into existence. Sorry if that isn't what you were looking for, but it is what you implied you were looking for.
If you want to be that pissy about it, here is a new google-fu to use: "when did newspapers stop using woodcuts". The very first article in it will start you down the path to the question you really had in mind: History of nineteenth-century periodical illustration - Nineteenth-Century Newspaper Analytics - NC State

the really fascinating thing was that photoetching was also used for the world first fax machine: 1843 by Alexander Bain (inventor) - Wikipedia[^]

I've seen a computer run out of a pizza box (on the Internet anyway) - just the mobo and drive and stuff sitting in a greasy box.
When I was young I put a 286 mobo and MFM HDD (remember those?) inside a cabinet with wood screws.
Soon I will be propping my PC up on 4 soup cans to give my 1000 watt PSU's fan some clearance to see if that solves my overheat problem when I use 4k rendering. Gotta wait for some adapters for my 2 remaining fans though before I try that.
Life goals are the setup from the movie Pi.

I use hockey pucks to hold things up - very sturdy and don't slip (as long as the surface isn't ice).
They also work great outdoors in the summer on top of a soda/beer can to keep the bees out.

A and B drive cables, getcha some.
WD st-225 perhaps?

I think it was. It certainly looks familiar - the "half" height one anyway, not the one that takes two bays. LOL

I actually had and used a ST-506 drive on my Amiga computer. This was I believe the first commercially available 5MB drive. Was a full height drive too, so took up a lot of space.
I remember too, was using it without a chassis, just plugged in with power and ribbon cable snaked out of the case. Sat beside the Amiga 2000 on the desk.

I dropped ST-225 and head 0 got damaged. I had to install inverters in both head select signals on the drive so the unusable head was now #3. BIOS didn't like the idea of head #0 being bad. I also wrote a driver for modified drive parameter block telling the DOS that the disk only had 3 heads. 15MB total instead of 20MB but it worked.
Later I 'upgraded' my XT to 486. The PC did not have regular chassis, it was a frame built from random aluminum rails. Mounting holes for new motherboard lined up with holes on XT motherboard so I installed 486 straight on top of XT on standoffs.
