InsertObject using VBA

I am running an Access DB as a desktop application, using Access2003 Runtime. I enter the InsertObject command in a Module attached to a form. In runtime, the screen opens, the InsertObject function opens, allows me to browse to select a *.bmp file, enters the graphic file into the form. When I close the screen and re-open the graphic file has disappeared. How do I get the file to remain in the form?
Thank you.
