Change images so you can’t click them

Hey everyone – my first wordpress post. I have created a couple of different wordpress sites already, mostly for friends or for a small businesses – I have edited php issues usually with no big issues, but I am having trouble with something. I am sure I am overlooking something very obvious, but I want to make sure that people who come to my wordpress site cannot click on the photos. Right now when they click on a photo it takes them to a blank webpage with the photo. If you go to my site and click on any photo you will understand.

The site is at:
https://www.1000rated.com

I am sure this was written into the theme I am using, but would love to have anyone’s help on removing it. Your help is very appreciated.
