Google image search brings this up pretty easily. (Image recognition technology is amazing these days.) It is The Abduction of Orithyia by Boreas, a late 17th century tapestry.
I gather it's currently in storage at a San Francisco museum rather than at a New England mansion.
I don't know uniforms well enough to be completely affirmative, but all your clues and the physionomy of the boy remind me of French Imperial Prince Napoleon, son of Napoleon III.
He was born in 1856 and the pictures on his wiki page show a strong ressemblance (in my humble opinion) with the boy on your photo. On this picture, he even wears a similar ...
This is a Railway (Reichsbahn) uniform from the period 1924 until June 1935.
The rank is probably Rangieraufseher (Shunting supervisor).
Railway Cap, 1924-1935-06
Rangabzeichen nach der Dienstkleiderordnung (DKO) 1924
DPSG Kluft 1930-1939

This was the Tannenberg Memorial, built near the town of Hohenstein, East Prussia (now Olsztynek, Poland).
Built in the mid-1920's, it was a monument dedicated to the German soldiers who fought in several battles in the area (two in WWI, and one from the 15th century). The design in the center is an iron cross, a symbol originally from the Kingdom of Prussia ...
Postcards produced on Kodak Professional AZO paper had 'AZO stamp boxes' on the reverse. The style of these boxes varied over time.
In this case, we have four triangles in the corners of the stamp box, two 'up' and two 'down'. This suggests that the card was produced in the date-range 1918-1930.
The ship name on the reverse appears to be 'USS Marica'. A ...
It's the Wedding at Cana.
The text is in Swedish, written with Gothic script (this was common up to the end of the nineteenth century in Sweden). The text is
... madd [sic!], som blir smakelig. Om Bröllopet i Kana i Galileen. JOHannis 2 Kap
... food that becomes well tasting. About the wedding in Cana in Galilee. Chapter 2 of John.
The website apparently originating this image has a fuller/bigger version of it:
From that we can conclude a few things:
The helmet wearing people are 'old warriors'. Since they are not even showing a face it stands to reason that the prophet himself and Ali are either meant or alluded to (a really strict observance of rules would even forbid that what ...
It's a Cветец (Svetetz), a device for holding a primitive torch called a Лучина (Luchina - splinter) or Rushlight, really just a splinter of wood or a piece of plant fiber dipped in grease.
The Svetetz would need to be placed in a pool of water to prevent dropped ashes from starting a fire, so that could explain the raised yoke-like sides of the wooden ...

It was in Glasgow in 1957, as part of the city's fight against tuberculosis. It's worth noting that the X-Ray machines weren't actually on the tram. It was simply used to advertise the campaign.

Mobile X-Ray units were used in the UK (the Mass Miniature Radiography (MMR) programme), but in vans, rather than trams. ...
It is, in fact, a twin-engined American P38 Lightning:
That particular aircraft was shot down on 27 January 27 1944. The wreck is located in Lecques Bay at a depth of about 40 meters, about one kilometre west of Grenier Point.
The wreck was discovered in November 1996, and identified as G15-LO (serial number 43-2545) flown by 2nd Lt. Harry Greenup of 49th ...
Found it. This is an RFC or Royal Flying Corp cap badge. I thought the picture was showing BBS but it's not. The angle, the quality of the picture and the loop for securing it to the bonnet was throwing me off. The women of the WAAC were often given the RFC badge when attached to airbases. These women were given the opportunity to travel to air bases in ...
It might be a Confederate flag, specifically the Van Dorn battle flag:
Quoting its wikipedia description:
The Van Dorn battle flag is a historical Confederate flag with a red field depicting a white crescent moon in the canton and thirteen white stars; and trimmed with gold cord. In February, 1862, Confederate general Earl Van Dorn ordered that all units ...
Confirming Brian Z and his answer: this is most likely a penumatic tube mail system. And strictly speaking: "What is the object moving…?" –
It's not a "cuboid box" but a cylindrical container, also called capsule.
Most easily visible in this still:
You see a darker edge on top, a lighter reflection of light at the bottom of the tube. On the right is a ...
Bunzlau is now in Poland and called Bolesławiec. Back then it was in Silesia, thus Prussia and therefore in Germany.
The photographer is given as "Otto Scholz", a German, not a Polish name, just as the address given is decidedly not Polish.
His studio is given as:
Fotografische Anstalt, vormals Ed. Scholz & Söhne in Bunzlau und Görlitz
If this is the relevant person:
(click to enlarge pictures)
then the actual salient points are:
cap: 'flying/winged wheels', double cockade -> Reichsbahn employee
shoulderboards to be expected as usual rank insignia: later than this timeframe, thus absent in this picture
before 1935: rank & section/specialty on display in gorget patches

A notable feature of this map is the English possession of Western France, which means that it's no later than 1453, when France took Bordeaux. Since in the Diplomacy game you color only the ownership of "supply centers" (represented by circles on the map, the larger industrial/population centres) this is consistent with France owning Paris, Rouen and ...
The identities of France and Britain are indicated by their heads of state, namely President Armand Fallières and King Edward VII respectively. There is also (as Roddy of the Frozen Peas observed in his comment above) a French flag on one of the ships near the French President.
The image appeared on the cover of the September 22, 1909 ...
A similar item was sold at an auction site here.
The item listed on that site is called a 'wild meat clamp' and is described as made to hold chicken legs or leg-of-lamb.
The French term Manche a Gigot (Thanks @LangLangC) will lead to many more examples in a search.
A tuareg takooba sword, maybe
Scabbard and half-moon markings on the blade are reasonably similar to a tuareg takooba sword shown on antiqueswordsonline. See images below: note that the half-moon markings appear at the same place as on the sword above, where the two outer fullers (grooves) end.
From a general description:
"The typical blade tapers, ...
This is a Taiwanese bankote with a face value of TWD $10. It depicts Dr Sun Yat-sen with the Presidential Office in Taipei on the reverse. The text says "Bank of Taiwan", the issuing authority, and "Year 59 of the Republic", i.e. 1960 in the Common Era. This date identifies when the printing plates were designed, not when the specific note was printed or ...
The machine the tractor is pulling is a grain reaper-binder, possibly a McCormick-Deering.
The reaper-binder, or binder, is a farm implement that improved upon the simple reaper. The binder was invented in 1872 by Charles Baxter Withington, a jeweler from Janesville, Wisconsin. In addition to cutting the small-grain crop, a binder also 'binds' the stems ...
The design is that of the "sailing ship" 10 Deutsche Mark note, a banknote first issued in 1960. The front features a 16th century painting by Lucas Cranach the Elder. On a real version of the note, the reverse would have depicted a barque of the same type like the German navy sailing ship Gorch Fock, officially meant to represent German openness to the ...
That looks a great deal like the Astoria Column, in Astoria, Oregon at the mouth of the Columbia River. In particular, the image from Wikipedia show a similar base and top part. While a bit difficult to pick out on your photo, you can also see the spiraling frieze of scenes from Oregon history.
As an aside, my grandfather was born and raised in Astoria in ...
The three man are, also according to the text, the three rectors present at a faculty meeting. The staffs they are carrying are rectorial staffs ("Rektorstab"), symbolising their honour and autonomous power over jurisdiction in matters regarding the university. It seems that in English this is similar to a staff of office and similar to ceremonial ...
The image shows shows the Fair at Lendit in France. It is taken from a 15th century manuscript held at the Bibliotheque Nationale in Paris France.
MS Latin 962 folio 264.
The suggested date for the manuscript is 1405-1410, which should help narrow down your research.
The whole manuscript has been scanned, and is available online.

From the portrait, it looks to be a William I (William the Conqueror) "bonnet-type" silver penny.
However, you should also be aware that there are a lot of replica and reproduction issues of that particular coin.
As noted by @SimonB and @richardb in the comments, your coin appears to have the letters 'WRL' stamped on the obverse, which indicates that it is ...
