How to call stored procedure with multiple parameters in an HTML expression

Question

Hi, Guys:
Can you show me an example to call stored procedure with multiple parameters in an HTML expression? I need to rewrite a procedure to display multiple pictures of one person stored in database by clicking button.
The orginal HTML expression is :
<img src="#OWNER#.dl_sor_image?p_offender_id=#OFFENDER_ID#" width="75" height="75">which calls a procedure as:
procedure dl_sor_image (p_offender_id IN NUMBER)now I rewrite it as:
PROCEDURE Sor_Display_Current_Image(p_n_Offender_id IN NUMBER, p_n_image_Count in number)could anyone tell me the format for the html expression to pass multiple parameters?
Thanks a lot.

Hi:
Thanks for your help! Your question is what I am trying hard now. Current procedure can only display one picture per person, however, I am supposed to write a new procedure which displays multiple pictures for one person. When user click a button on report, APEX should call this procedure and returns next picture of the same person. The table is SOR_image. However, I rewrite the HTML expression as follows to test to display the second image.
<img src="#OWNER#.Sor_Display_Current_Image?p_n_Offender_id=#OFFENDER_ID#&p_n_image_Count=2" width="75" height="75"> The procedure code is complied OK as follows:
create or replace
PROCEDURE Sor_Display_Current_Image(p_n_Offender_id IN NUMBER, p_n_image_Count in number) AS
    v_mime_type VARCHAR2(48);
    v_length NUMBER;
    v_name VARCHAR2(2000);
    v_image BLOB;
    v_counter number:=0;
    cursor cur_All_Images_of_Offender is
      SELECT 'IMAGE/JPEG' mime_type, dbms_lob.getlength(image) as image_length, image
      FROM sor_image
      WHERE offender_id = p_n_Offender_id;
    rec_Image_of_Offender cur_All_Images_of_Offender%ROWTYPE;
BEGIN
    open cur_All_Images_of_Offender;
    loop
      fetch cur_All_Images_of_Offender into rec_Image_of_Offender;
      v_counter:=v_counter+1;
      if (v_counter=p_n_image_Count) then
        owa_util.mime_header(nvl(rec_Image_of_Offender.mime_type, 'application/octet'), FALSE);
        htp.p('Content-length: '||rec_Image_of_Offender.image_length);
        owa_util.http_header_close;
        wpg_docload.download_file (rec_Image_of_Offender.image);
      end if;
      exit when ((cur_All_Images_of_Offender%NOTFOUND) or (v_counter>=p_n_image_Count));
    end loop;
    close cur_All_Images_of_Offender;
END Sor_Display_Current_Image; The procedure just open a cursor to fetch the images belong to the same person, and use wpg_docload.download_file function to display the image specified. But it never works. It is strange because even I use exactly same code as before but change procedure name, Oracle APEX cannot display an image. Is this due to anything such as make file configuration in APEX?
Thanks
