Oracle Intermedia / Image Import

Hello.

I'm having trouble importing images. I have the following procedure :

declare

    Image ORDSYS.ORDImage;
    ctx RAW(4000) := null;

begin

    insert into bilde_test values (
    4, null, ORDSYS.ORDImage.init(), ORDSYS.ORDImageSignature.init());

    SELECT PHOTO into Image FROM bilde_test WHERE photo_id = 4 for update;

    Image.SetSource('file', 'LARSDIR', 'logo_phpBB.gif');     Image.importFrom(ctx, 'file', 'LARSDIR', 'logo_phpBB.gif');

    UPDATE bilde_test SET photov = Image where photo_id = 4;     commit;
End;

When I try to execute the procedure, I get the following error report. (It's in Norwegian, so I've tried to translate the norwegian text) :

declare

ERROR on linj 1:

I've tried several other procedures, with the same result. Seems like 
the trouble occurs around the "import" statement.
