Oracle and MSAccess working with pictures

Hi,
I have a little problem. I create an Oracle table with column to store images (type long raw). And I'd like to fill it from linked table in MS Access. When open this column Access says this is a OBJECT OLE type. And to store there data I must select from menu Insert Object (e.g bitmap picture). So far no problem. But when I close table an error occure (update linked table faild). So I'm not able to insert any pictures from Access to Oracle.

Please anyone knows the solution, help me.

Thanx                             Michal Strelec.
