Would need more info on the tools used to look at the files and what Win
OS was used.

It possible that the "icons" that were cut and pasted by a windows
explorer tool automatically include all three files. But I've never
heard of that before.

Some GUI viewer tools on Linux and Win automatically create thumbnails
the first time you open the file.

its possible that whatever version of Windows your son is running has a
non-default action set up for handling jpg's.

But without more info all of the above is just speculation.

Can you SMB mount the Win file system to your Linux system and do an
"ls -lags " on the directory?
