Need help with image post

Hello everyone

I post a image to my wp website. When I click on this pic, the site send me to pic page.

I want if any one click on this pic, the pic will zoom and not send me to new page.
I have pluged Image Zoom, but still not working.
Here is my site and click on a pic and the site will send you to a new page. I want the pic becomes larger (zoom).
