issue when export/import table including pictures

Hi,

As i did not get any answer yesterday i'm asking it again.
I have a table with pictures stored as bytea field.
I'm able to export them from my database hosted by my web supplier.
However, when i try to import them to my local database, i get 2 types of
error message (based on how i import them)

1. if import is done by SQL -> run SQL script in phppgadmin : error message
is " No server supplied!"
2. if import is done by Import function from a table in phppgadmin : error
message is "Import error: File could not be uploaded to the server"

here is a sample of my export table in SQL format :

--SET client_encoding = 'UTF8';
--SET standard_conforming_strings = off;
--SET check_function_bodies = false;
--SET client_min_messages = warning;
--SET escape_string_warning = off;

SET search_path = immense, pg_catalog;
SELECT pg_catalog.setval('photo_photo_id_seq', 30, true);
INSERT INTO photo VALUES (1, 1, '2007-02-25 00:00:00',
'\\377\\330\\377\\3412\\004Exif\\000 ..... 32E\\303\\215\\235?\\377\\331');

i truncated the last field due to its length :-)
SO as i have such problem with phppgadmin, i use pgadmin GUI under windows.
But pgadmin deletes the bytea information in thie INSERT INTO SQL command
:-( and i do not know why.
what could be the problem ?
thanks for your help.
