Can Smush Pro change which version of the image is loaded by default?

A lot of my images have been uploaded at a very high resolution making the images very big and slow. Smushing them has created a bunch of smaller versions which are dramatically smaller in file size but the browser still seems to load the large versions of the images.

Is there a way to automate this so that I don't have to go throught the entire site relinking all the images?

Thanks
