Thread:Talk:RPi-Cam-Web-Interface/Changing contents of Preview stream

So, I am having fun with my RPi and cameras, getting the preview from many into a single web page, into a Python script and into OBS. What I cannot seem to do is change the content of the preview to be the same as the captured image. Is there a way to do this. The preview seems to contain only the centre of the image captured by the camera module. Any ideas please.
