Go through the above site...

Using package as follows will make it Dynamic.

Pass Img_Type = 'image/gif' for gif. 'image/pdf' for pdf etc.

create or replace package image_get
as
procedure img( p_id in demo.id%type, Img_Type in varchar2);
end;
/

create or replace package body image_get
as

procedure img( p_id in demo.id%type, Img_Type in varchar2 )
is
l_lob blob;
l_amt number default 30;
l_off number default 1;
l_raw raw(4096);
begin
select theBlob into l_lob
from demo
where id = p_id;

-- make sure to change this for your type!
owa_util.mime_header( Img_Type );

begin
loop
dbms_lob.read( l_lob, l_amt, l_off, l_raw );

-- it is vital to use htp.PRN to avoid
-- spurious line feeds getting added to your
-- document
htp.prn( utl_raw.cast_to_varchar2( l_raw ) );
l_off := l_off+l_amt;
l_amt := 4096;
end loop;
exception
when no_data_found then
NULL;
end;
end;

end;
