Question about psql for win32

Hi,
can someone tell me how to import a large object which is located on a
win32 machine?
On the postgres host the following statement works fine:

INSERT INTO fotos (name, raster)
VALUES ('some text', lo_import('/bilder/b000001.gif'));

How must the above look like if I try to import a file from another
unix-machine and how does it work with psql for win32 if the file to import
lies on the Windows machine???
Thanks for help. Please mail to my address I've not subscribed.

Regards Rolf
