I'm not real clear on what you're trying to do.  But it sounds like
you want to run imview or some other program once, and have your
program tell that program to display a new image whenever it wants to
display something new.  In order for that to work, the image displayer
has to be set up to accept that kind of communication.

However, if by "imview" you mean the program documented at
http://hugues.zahlt.info/software_imview.html, that program appears to
have a server mode.  So you'll need to run it in server mode and then
communicate with it via a TCP/IP socket.  The documentation should
explain how to do this, but I haven't looked over it carefully.

I hope this is helpful.  I don't really know anything about this
program and just did a quick Google search to see if I could come up
with something helpful.  But it might be just what you're looking
for.  If it's not helpful at all, sorry.
