Forms :: Display Images On A Form In A Split Database

Am trying to display images on a form in a split database. I add the attachment field to the associated form's table and add the attachment control to the form but cannot get the image(s) to display on the form (the control remains blank). I can add the image(s) in table view (and display them) but double clicking on the form control also does nothing.

I think I must be doing at least the basics correctly as if I try the same thing to an earlier, non-split version of the database, all works as expected.Are there additional steps required to do this thing in a split database?
