Need help to show a thumbnail image column in report

Question

Hi, Gurus:
I need to display a column of thumbnail images in a classical report. I follow the thread https://kr.forums.oracle.com/forums/thread.jspa?threadID=2201667
I am using APEX 4.1, Oracle 11gR2
Here is my table:
CREATE TABLE "SORS"."SOR_IMAGE"
   (     "IMAGE_ID" NUMBER(10,0),
     "OFFENDER_ID" NUMBER(10,0) NOT NULL ENABLE,
     "IMAGE" BLOB CONSTRAINT "SOR_IMAGE" NOT NULL ENABLE,
     "THUMBNAIL" BLOB,
     "MIME_TYPE" VARCHAR2(50 BYTE),
      CONSTRAINT "SOR_IMAGE_PK" PRIMARY KEY ("IMAGE_ID")
)Here is my procedure:
create or replace
procedure dl_sor_thumbnail (p_offender_id IN NUMBER) as
   v_mime_type VARCHAR2(48);
   v_length NUMBER;
   v_name VARCHAR2(2000);
   v_image BLOB;
BEGIN
  SELECT 'IMAGE/JPEG', dbms_lob.getlength(thumbnail), thumbnail
  INTO v_mime_type, v_length, v_image
  FROM sor_image
  WHERE offender_id = p_offender_id
  and image_id = (select max(image_id)from sor_image where offender_id = p_offender_id) ;
-- setup the HTTP headers
owa_util.mime_header(nvl(v_mime_type, 'application/octet'), FALSE);
htp.p('Content-length: '||v_length);
--htp.p('Content-Disposition: attachment; filename="' || substr(v_name, instr(v_name,'/') + 1) || '"');
--htp.p('Content-Disposition: attachment; filename="'somemmmmmfilename.jpg'");
-- close the headers
owa_util.http_header_close;
-- download the Photo blob
wpg_docload.download_file (v_image);
END dl_sor_thumbnail;here is my report:
select distinct 'MAP', '<img src="#OWNER#.dl_sor_thumbnail?p_offender_id='||so.offender_ID||'"/>' detail,

and ((so.weight-:P5_TF_WEIGHT between -25 and 25) or (:P5_TF_WEIGHT is null))and I set detail column as standard report column.
however, the report shows no image, just an icon which indicates the image is not available. Would anyone help me on this problem?
Thanks a lot.
Sam

Bad choice. Only one person involved in that thread knew what they were doing...and you copied from the wrong one.
Here is my procedure:Lose it. Custom download procedures are overcomplicated and now almost never required.
See the recommendation to use declarative BLOB support, as shown in the Thumbnail image problems.
