No, it just serves a (mostly) blank document and relies on scripts to
fetch and insert the actual content. Bad style, but unfortunately not
uncommon, and hardly an obstacle to anybody who wants to download and
store the content locally.

Have you tried Google? Searching for "X-Wix" shows the tool used to
create the site as the first result.

In general, serving typical web content (text and images) and at the
same time expecting visitors to be unable to download it is pointless.
If you don't want your content to be available on the Web, don't publish
it there. Otherwise, "collectors" will find a way to get what they want.

Out of curiosity, I tried copy/pasting, saving the HTML (with and
without assets) locally, saving individual images, and printing the
whole page. Everything worked just as expected, which leads me to
suspect that your friend may not be very technically savvy himself.

What will not work anymore is using a simple crawler program to mirror
the complete site. This tool would have to be able to execute
JavaScript. I know at least one "collector" who uses just such a
program, and who has already pretty much copied the whole website. They
are currently serving smaller versions of the artwork on their own site:

For the big guns in copy protection on the web, you should look into
Encrypted Media Extensions. Complete overkill for a small gallery site,
but at least it will keep that pesky GoogleBot away.
