How to Display an Image on my FORM

Question

Good Day!
I would like to ask some help from you guys with my problem on how to display an image on my form. I would like to display my uploaded image on my form but instead of an image, the get_blob_file is showing. By the way, I'm using Apex 4.1
I downloaded the Order Entry Sample Application and followed the Page 6, the Product Details. I even made snapshots of each details from Page Rendering to Page Processing in order not to miss a thing.
At the moment, I was able to upload or store the image on my created Oracle table and also able to retrieve it on the Download Link Text with Content Disposition value of Inline, provided by APEX Settings. If I invoke the Download link beside the file browser, a page with the image will be shown, below is the address:
http://127.0.0.1:8080/apex/apex_util.get_blob_file?a=200&s=339877802936975&p=230&d=7107921433296839&i=7107601420296838&p_pk1=54&p_pk2=&p_ck=7D6512D967336C4B94258EEA3CDF1BE6&p_content_disposition=inline
However, instead of showing the image on a region, below is the one showing on my Form:
<img src="apex_util.get_blob_file?a=200&s=339877802936975&p=230&d=7107921433296839&i=7107601420296838&p_pk1=54&p_pk2=&p_ck=7D6512D967336C4B94258EEA3CDF1BE6" />
As you can see the parameter values are the same but I know I missed something that's why I'm here :)
I would highly appreciate all the help you can provide and many thanks in advance.
I tried to change gear by making an html region of type PL/SQL (anonymous block) and a procedure but still no image :(
Below are the scripts.
declare
cursor cur is
select *
from wsemployee
where empid = :P230_EMPID;
begin
for rec in cur
loop
IF rec.mime_type is not null or rec.mime_type != '' THEN
htp.p( '<img src="my_image_display?p_image_id='||NVL(rec.empid,0)||'" height="'||100||'"/>' );
else
htp.p( 'No Image ');
END IF;
htp.p( ' ');
end loop;
end;
PROCEDURE
create or replace PROCEDURE my_image_display( p_image_id IN NUMBER)
AS
l_mime VARCHAR2 (255);
l_length NUMBER;
l_file_name VARCHAR2 (2000);
lob_loc BLOB;
BEGIN
SELECT MIME_TYPE, PHOTO_BLOB_CONTENT, PHOTO_FILENAME,DBMS_LOB.GETLENGTH(photo_blob_content)
INTO l_mime,lob_loc,l_file_name,l_length
FROM wsemployee
WHERE empid = p_image_id;
-- set up HTTP header
-- use an NVL around the mime type and
-- if it is a null set it to application/octect
-- application/octect may launch a download window from windows
owa_util.mime_header( nvl(l_mime,'application/octet'), FALSE );
-- set the size so the browser knows how much to download
htp.p('Content-length: ' || l_length);
-- the filename will be used by the browser if the users does a save as
htp.p('Content-Disposition: attachment; filename="'||replace(replace(substr(l_file_name,instr(l_file_name,'/')+1),chr(10),null),chr(13),null)|| '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
END my_image_display;

Hi Ying,
you can add a UDF to the table spp2 with a programm
but the table is not yet listed in the 'Manage User Fields' form.
there's no way to "enable" it - sorry
