LONG RAW images from remote db display in APEX

Question

How do you display long raw images in APEX(Application Express 2.1.0.00.39) from a remote db?
The code below works in 9i db MOD_PLSQL
CREATE VIEW PICTURES AS(
SELECT PICTURE_OBJECT_ID,
PICTURE_DATE,
PICTURE_OBJECT_TYPE
FROM REMOTE_PICTURES@DATABASE_LINK);
CREATE OR REPLACE PROCEDURE JPG (
p_id IN pictures.picture_object_id%TYPE
IS
s_image LONG RAW;
l_amt NUMBER DEFAULT 30;
l_off NUMBER DEFAULT 1;
l_raw RAW (4096);
BEGIN
SELECT pictue_data
INTO s_image
FROM pictures
WHERE pictue_object_id = P_ID
and pictues.pictue_object_type = 'EMPLOYEE';
OWA_UTIL.mime_header ('image/jpg');
BEGIN
LOOP
DBMS_LOB.READ (s_image, l_amt, l_off, l_raw);
HTP.prn (UTL_RAW.cast_to_varchar2 (l_raw));
l_off := l_off + l_amt;
l_amt := 4096;
END LOOP;
EXCEPTION
WHEN NO_DATA_FOUND
THEN
NULL;
END;
In 9i this was called like. (HTML tags have been modified to display in post.)
htp.tablerowopen;
htp.p('<>td valign=middle align=center<>');
htp.p('<>IMG SRC="/pls/dad/jpg?p_id='|| v_picture_object_id ||'"<>');
htp.p('<>/td<>');
htp.tablerowclose;
I am trying to get the same thing to work in APEX. I have tried this in APEX(Application Express 2.1.0.00.39) sql report region and specifying the image to display in link column by doing:
<>img title="#IMAGE#" src="/apex/#OWNER#.jpg?p_id=#IMAGE#" width="57" height="75" /<>
Any suggestions would be helpfull. I can not migrate the long raw data type due to restrictions.

Vikas,
I have tried to find/produce error, but no luck. All I have is a blank image holder area the size specified in the <>img tag. How can I produce a visable error? I have tried to run the procedure from sqldeveloper with no luck. I used to have a tool (plsql developer) where I could test the pocedure and see the actual (image)output, but the version is not compatible with 10g. I will read the link.
