Image Size on Product Page

I am playing around with the AIOSRS, and I really like it. One question I have is the image on the product page. It’s static. What I am wondering is whether or not there is a setting that I am not seeing that can make it a link to a larger image? Or can I at least make it a bigger image? I am guessing that the latter question is a no since this is what is supposed to be displayed in Google searches, but I thought I’d ask. The link to the test product I am using is Trailer Image

Thanks in advance
