Using Oracle 8.0.5 Here is what I did:

---

---

CREATE TABLE item_images (

   inventory_item_id NUMBER NOT NULL,
   item_image BFILE default NULL    )
/

insert into item_images values (5112277, BFILENAME('BFILE_DIR', 'pin.gif'))
/

insert into item_images values (5112279, BFILENAME('BFILE_DIR', 'lip.gif'))
/

commit
/

---

---

Then I read the file into a buffer:

---

---

DECLARE
   Lob_loc BFILE;
   Buffer RAW(1024);
   Amount BINARY_INTEGER := 1024;
   Position INTEGER := 1;
BEGIN
   /* Select the LOB: */
   SELECT item_image

       INTO Lob_loc
     FROM test_item_images

   WHERE inventory_item_id = 5112277;
   /* Opening the BFILE: */
   DBMS_LOB.FILEOPEN (Lob_loc, DBMS_LOB.FILE_READONLY);    LOOP

      DBMS_LOB.READ (Lob_loc, Amount, Position, Buffer);
      Position := Position + Amount;

   END LOOP;
   /* Closing the BFILE: */
   DBMS_LOB.FILECLOSE (Lob_loc);
   EXCEPTION
   WHEN NO_DATA_FOUND THEN
      DBMS_OUTPUT.PUT_LINE('End of data'); END;

So far everything is fine, but ...
How can I retrieve the image file (which is now in the buffer variable) and display it on a web page or in any other gif image viewer? Your help is greatly appreciated.
