Display picture in blob on report with GET_BLOB_FILE_SRC

Question

Hi Guys !
I want to display picture contains in blob on my report. The function GET_BLOB_FILE_SRC can do that but I must have an File browse item to use them.
The only other way I know is to create my own function that return my image. Like that :
create or replace
PROCEDURE "GET_FILE" (p in number) as
v_mime varchar2(255);
v_length number;
v_file_name varchar2(2000);
Lob_loc BLOB;
BEGIN
select mime_type, blob_content, name,dbms_lob.getlength(blob_content)
into v_mime,lob_loc,v_file_name,v_length
from file
where id = p;
-- 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(v_mime,'application/octet'), FALSE );
-- set the size so the browser knows how much to download
htp.p('Content-length: ' || v_length);
-- the filename will be used by the browser if the users does a save as
htp.p('Expires: ' || to_char(sysdate + 1/24,'FMDy, DD Month YYYY HH24:MI:SS') || ' GMT');
htp.p('Content-Disposition: attachment; filename="' ||
substr(v_file_name,instr(v_file_name,'/')+1)|| '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
end adu;
The only benefit to use GET_BLOB_FILE_SRC is for specify format of my image ?
