Hi Kevin,

That should be

  eval exec [auto_execok start] [list "" "my photo.jpg"]

a) You need a "" for the "title" argument to START (check out
START/?). Otherwise, when the first argument is quoted, START will
treat that as a title. And the filename will be quoted when it
contains spaces. This is on NT/W2K, I don't know about W9x/Me.

b) You need [list] to offset the [eval] when your you do a) and/or
when your filename contains spaces.

The easiest on Windows is probably to write or re-use a binary
extension that wraps the ShellExecute API, like the one on
e.g. <http://wiki.tcl.tk/13925>.

You might want to look at what the Portland project plans with their
"xdg-utils" <http://portland.freedesktop.org>. They cover the same
ground here.
