No, I already tried. That's because the program I use (HDFView) is
expecting 0, 1 or more arguments, each one separated by a space. In
your case it would try to open 3 files :
D:\my
dir\my
photo.jpg

So we have on one hand a valid IDL string (I can compile a routine
containing it and print it). On the other hand exactly the same
command can be used manually in Windows shell (cmd.exe) using copy/
paste.
BUT using it as argument in SPAWN causes malfunctions with double-
quotes ( " ).
As I said earlier, using the /NOSHELL keyword (thereby bypassing the
use of a shell, see IDL Help) solved the issue.

Anyway, thanks for your help !
