I was going to suggest using FindExecutable to find out whatever
your system uses to show pictures... but then I tried it out and
found out that the association is actually via the shimgvw DLL.
So I suppose you'll have to special-case that.

<code>
import win32api
import subprocess

filepath = r"c:\temp\test.jpg"
res, exe = win32api.FindExecutable (filepath)
if exe.endswith ("shimgvw.dll"):
   cmd = "rundll32.exe %s,ImageView_Fullscreen %s" % (exe, filepath)
else:
   cmd = "%s %s" % (exe, filepath)

subprocess.call (cmd)

</code>

On my XP machine this waits for the ImageViewer to return.
Be interesting to see if that's different under Vista. At
least it offers you a little more control, perhaps?
