Most of the pyplot functions return some kind of plot object. You
don't have to care too much right now. Basically the call to imshow()
creates the necessary plot object and then you need to call
pyplot.show() to make the plot appear. If your working environment is
set up in a particular way, it may not be necessary to call show(),
which is probably why the example you are following doesn't include a
call to show().

Questions related to plotting with Matplotlib are best asked on the
matplotlib-users mailing list, you can subscribe here

Also have a look at the pyplot tutorial
