Answer 1

Check the sample application and adjust it to your needs. Here is some code from that application:
select p.product_id edit_product, p.product_id view_product_id, p.product_name, p.product_description, p.category, p.product_avail, p.list_price, '<img src="#OWNER#.custom_image_display?p_image_id=' || nvl(i.image_id,0) || '" height="50" width="50" />' img
from demo_product_info p, demo_images i
where p.image_id = i.image_id (+)
(cant paste source above corectly because of html tags in it)
CUSTOM_IMAGE_DISPLAY is a procedure:
create or replace procedure custom_image_display (p_image_id in number)
as
l_mime varchar2(255);
l_length number;
l_file_name varchar2(2000);
lob_loc BLOB;
begin
select mime_type, image, image_name, dbms_lob.getlength(image)
into l_mime, lob_loc, l_file_name, l_length
from demo_images where image_id = p_image_id;
-- Set up HTTP header
-- Use an NVL around the mime type and if it is a null, set it to
-- application/octect - which may launch a download window from windows
owa_util.mime_header(nvl(l_mime,'application/octet'), FALSE );
-- Set the size so the browser knows how much to download htp.p('Content-length: ' || l_length);
-- The filename will be used by the browser if the users does a "Save as" htp.p('Content-Disposition: filename="' || l_file_name || '"');
-- Close the headers
owa_util.http_header_close;
-- Download the BLOB
wpg_docload.download_file( Lob_loc );
end;
