How to display an image in a report ?

Question

I put the following code into the PLSQL - section <after header is shown>:
declare
v_str varchar2(2000);
v_rowid varchar2(200);
begin
select ROWID into v_rowid from mytable where id=1;
v_str:=htf.img(curl=>'http://rdspc23/pls/portal30/PORTAL30.wwa_app_module.file_download?p_block=DEFAULT&p_object=BILD&p_source='&#0124; &#0124;PORTAL30.wwv_htf.url_encode(v_rowid));
htp.p(v_str);
end;
(This code is extracted from a form and inserted in my report.)
If the image is in the browser-cache i can see the image and everything works properly. If the image is not in cache then there is only a broken link.
When i try the link in a separate browser window the folloing error message appears:
No data returned from stored procedure
The PL/SQL gateway invoked a stored procedure as part of processing the URL but the procedure returned no data.
What can i do to insert an image in a report.
Are there any documentation for the plsql-packages which portal is using ?

I tried it doing it this way and it worked -
1. copy the image into the directory aliased in 9iAS configuration file as '/images/'.
2. In the PL/SQL code section after header, I write the following code -
begin
htp.p('<img src="/images/pobexp.gif"/>');
end;
