Events Category Pages

Hi All,
I’m having a really hard time trying to replace the text and image on the default events calendar page. Here’s what it looks like with a banner bg image and text: http://dinoandkidz.com/_site/parent-zone/

But if you click on any of the location calendar the stock image (kids hand) and text are there and I don’t know where or how to replace it: http://dinoandkidz.com/_site/events/category/brampton/

Please help any suggestions would be appreciated as I tried searching the widgets, looked up the source code but I found nothing.
