I was astonished myself when I looked at the rather complicated code  I 
put together some time ago, but did not have time to try out and 
recommend a script that would have been nearer to Ken' needs.

The "ask file" command used in my example returns as "it" something like

"C:/Dokumente und Einstellungen/Besitzer/Desktop/Meta2.6a2/Testimage"

which had to be parsed into directory and short file name using the last 
slash.

Of course, Ken need not use "ask file", if he knows where to store the 
images.

He could just use the "export snapshot" command which can include 
setting the directory and file name.

Beste Gruesse,
