How to get a Windows File Explorer Wi-Fi connection to Android to show photo thumbnails?

It's not so much an FTP problem per se. Paul's
quoted snippet explained it pretty well. To generate
a thumbnail, something has to load the whole image
and create a resized version. It's very work-intensive.
And it can't be done without loading the original,
whether that's 50 KB or 20 MB.

Yes. But. The thumbnail on Android already exists.

It's just that the Android .thumnail is in Android thumbnail format and not
in a Windows thumbnail format.

So the hope is that an Android-thumbnail-to-Windows-thumbnail conversion
exists.

If thumbnail generation is done by Windows Explorer
then Windows has to have the original images. As Paul
noted, it would be a bit silly to import the whole data
load in order to create thumbnails, in order to see if
you want to import any data. You might just as well
copy all the images over to begin with.

Exactly!

You have to remember that all of this is just data
transfer. Likewise with a webpage: We talk about
visiting a website, but really it's nothing like that.
The browser calls an IP address and says, "Please
give me your index.html." The server sends that. The
browser then parses it and calls again to get the files
that make up the webpage: "Please give me pic.gif,
pic2.gif and styles.css." The server sends those.
Eventually the browser has the whole thing and puts
it together, following the instructions in the HTML
and CSS, to show you a "homepage".

True that.

The FTP protocol is being used with FileZilla or WinSCP or even with
Windows File Explorer, and then the client (FileZilla, WinSCP, or Windows
File Explorer) 'reconstructs' the data.

There's often similar confusion when people access
ZIP files. Microsoft made it very convenient to see
the files as though they're in a folder. In their attempt
to make ZIPs easy to use they created massive confusion,
because the files are not in a folder, on disk. They're
still part of the ZIP, compressed.

Good analogy!

What you could possibly do would be to install
a thumbnail generator on Android and batch-convert
your images, maybe creating a folder in the same
location.

Exactly what I was asking for!
Does such an Android-to-Windows .thumbnail conversion exist?

You might try posting one of the files. If it's some
kind of cache library it might not work, but if
each thumbnail is a separate file then the extension
might just be a cutesy way to label a small JPG.
