I'm using a subplot but I want to use imshow(img) in one section of the subplot and want to simply 'plot()' something in another section. Does this work? Whatever examples I have seen on MATLAB pages is either all should have imshow or all should have plot. both don't work together it seems?!

This is possible by setting the parent axes in your call to imshow:
subplot(1,2,1);
plot(rand(10,1));
ax = subplot(1,2,2);
imshow('peppers.png', 'Parent', ax);

In that case, you don't even need to worry about Parent and ax -- it will show the image in the second subplot even without using them.
subplot(1,2,1);
plot(rand(10,1));
subplot(1,2,2);
imshow('peppers.png');
I do it all the time.

Oh nice thanks for the tip! I shouldn't have assumed it would be needed.
Besides looks like I may have misinterpreted the Q, whoops.

If you have a subplot and want to show both an image and a plot in the subplot, please see my attached inset demos.
