Import image into postgresql database - Mailing list pgsql-admin

Dear all,
i have a question for you: I would like to store  images (jpg) into a table of
postgresql database. My question is : what is the corret type of tables filed
that i have to use? Reading some forum of article in the net there are two
ways: bytea or oid type. Whati is the best type to store my images?
I tried to insert in both ways. With oid type i able to insert images, but
with bytea i don't understand how store it .
i create a test table:

CREATE TABLE public.images
(
  imgname text,
  img bytea
)

and i tried many ways:


NSERT INTO images (imgname, img)
VALUES ('beautiful image', bytea_import('C:\\9999.jpg'));

or

INSERT INTO  images (img) VALUES (pg_escape_bytea('C:\\9999.jpg'))

but it doesn't work.
So How can i solve my problem? and another question.. If i able to store my
image into bytea fiels..how can i export it for see it for example with paint?

Thanks
