Display Image in Report Colum, ORA-06502: PL/SQL whe column format is set

Question

Hi @all
i created a small table
CREATE TABLE my_sal201 (
grafikdid VARCHAR2(38) NULL,
grafik BLOB NULL,
mimetype VARCHAR2(255) NULL
then i inserted one column with a page process
BEGIN
IF (:p6_filename IS NOT NULL)
THEN
INSERT INTO my_sal201
(grafikdid, grafik, mimetype)
SELECT meb_ora.mkdid(), blob_content, 'image/gif'
FROM wwv_flow_files
WHERE NAME = :p6_filename;
DELETE wwv_flow_files
WHERE NAME = :p6_filename;
:p6_filename := NULL;
END IF;
END;
after that i want to show the columns and the image in a report. so i created a report in a new region quite similar to the example in the obe
it works fine, the image columns is shown as "[datatype]"
whenever i change the format of the image colum of the report to
DOWNLOAD:MY_SAL201:GRAFIK:GRAFIKDID::::::inline:Herunterladen
(just one example, IMAGE:... does not work as well)
no more rows are shown but the error h3. "ORA-06502: PL/SQL: numerischer oder Wertefehler: Fehler beim Konvertieren von Zeichen zu Zahl"
what did i do wrong?

i'm to silly to work with images :-ß
i did copy ur example to another app on http://apex.oracle.com/pls/otn/. fine->igames are shown.
on a new page in my local app, i did exactly the same (create a table, procedure, ect) it does not work.
rows are shown inthe report, but no images, instead the icon for a broken/missing image is displayed.
i tried to debug using firebug:
in the sample app on otn, when i point the mnouse over the procedure call, the image appears in a tool-tip
in my app, the code is quite simmilar, nothing happens. no icon

<img width="50" height="50" src="WMF_GL_INTMAN001.DISPLAY_IMAGE?inID=1"/>
