Well, it's completely possible to create a file name like:

This is my *favourite* photo from "Cats" \ by Bob & Jane / my wife ~ 2008 `musical'.JPG

What a fun handling this. :-)

Call me old fashioned, but I don't mind making things more
complicated than it should be. The space character is the
command argument separator, as well as / is the root directory
and * is "everything". Applications like xmms can even replace
the _ by a space when showing the filename of an mp3 file (given
that no ID3 tag is provided). So I avoid spaces generally, and
when I get files with spaces, I do convert the names automatically.

That's correct; find can provide file names including paths and can
furthermore explude directories from being in the list (-type f).

In your script, $x contains the filename with spaces and should
be passed as one value to the program called.
