If it is Version 10, then the way xseethru works is magic (if I remember correctly.) If it is Version 11, then you should be able to actually create windows with a background color of "Transparent" that will allow you to see thru to the image planes. In fact, you can actually set the root window to transparent on X 11 with the command xsetroot -solid transparent assuming that you have a color cell in the colormap available. In fact that is the mode that I prefer to work in (in that configuration.) This makes it seem as though the windows are simply "floating" over whatever image you have in the image planes.
