Invalid BLOB Length - Mailing list pgsql-interfaces

I am using Borland C++ Builder 3.0 with PostgreSQL 6.4.2 and the
latest ODBC driver from ftp.postgresql.org.

I created a table users that looks like this:

CREATE TYPE lo (
    internallength = 4,
    externallenght = 10,
    input = int4in,
    output = int4out,
    send = int4out,
    receive = int4in,
    default = '',
    passedbyvalue);

CREATE TABLE users (
    userid int4,
    username varchar(255),
    userimage lo);

When I try and insert an image, the app returns "Invalid BLOB Length".

What am I doing Wrong?

Thanks
