Hi,
I am using oracle database 10g release2(10.2.0.1.0) and i upgraded it with apex_3.2.1. and this is the code and table which i used to display the images in my application.
CREATE TABLE  "STUDENT_PERSONAL_DETAILS"
   (     "S_NO" NUMBER NOT NULL ENABLE,
     "STUDENT_ID" NUMBER NOT NULL ENABLE,
         "STUDENT_IMAGE" BLOB,
         "MIMETYPE" VARCHAR2(255),
         "FILENAME" VARCHAR2(400),
        "IMAGE_LAST_UPDATE" DATE,
       CONSTRAINT "STUDENT_PERSONAL_DETAILS_CON" PRIMARY KEY ("STUDENT_ID") ENABLE
CREATE OR REPLACE PROCEDURE  "MY_IMAGE_DISPLAY_STUDENT" (p_image_id IN NUMBER)
AS
   l_mime        VARCHAR2 (255);
   l_length      NUMBER;
   l_file_name   VARCHAR2 (2000);
   lob_loc       BLOB;
BEGIN
   SELECT MIMETYPE,STUDENT_IMAGE, FILENAME, DBMS_LOB.getlength (STUDENT_IMAGE)
     INTO l_mime, lob_loc, l_file_name, l_length
     FROM STUDENT_PERSONAL_DETAILS
    WHERE STUDENT_ID = p_image_id;
   OWA_UTIL.mime_header (NVL (l_mime, 'application/octet'), FALSE);
   HTP.p ('Content-length: ' || l_length);
   OWA_UTIL.http_header_close;
   WPG_DOCLOAD.download_file (lob_loc);
END my_image_display_student;
<TR BGCOLOR="#DEB887">
<td ><left><B>Father Name</b></td>
<td ><left>'||INITCAP(REC.FATHER_NAME)||'</td>
<td rowspan="6" colspan="2" ><center>
<img src="#OWNER#.my_image_display_student?p_image_id='
|| :P10_STUDENT_ID || '" /></td>
