knowledge there is no similar notation for shared network folders. What you can
do is the following:
the image with a drive letter, e.g. Z:. Use the "exe=" option of the
image command to name a .bat file that is executed if the image is not found. In
this .bat file, you can assign the drive letter Z: using a user name and
(1,80) "Z:\x.jpg" exe="assign_drive.bat"
use Z: \\DISCSTATION\Synactive\temp password /USER:username"
An inconvenience of
this approach is that it assumes that the drive letter Z: has not yet been
assigned on the user's PC.
