Hi,

What happens if you put another window in front of the pixmap (after
you have shown it) and then uncover it - maybe you have to cause it 
to redraw.

Or perhaps you could destroy it and create a new one:

  $form->{'pixmap7'}->destroy;  
  $form->{'pixmap8'} = new_from_file Gnome::Pixmap("file.xpm" );
  $form->{'frame233'}->add($form->{'pixmap8'} );
  $form->{'pixmap8'}->show;

I don't know what the memory costs of this are - I guess that the 
original pixmap will hang around until you destroy the form and every
reference to it but I don't know - perhaps you can work it out.
