Scale(close up) the image when hover

Hello everyone, I got a trouble. I using the freelancer theme which hover the image then get in the modal. I want close up the image when I hover. I tried many times but it seems fail, only make the hover background (cooler one) bigger or make my hover text disappear.... Many Thanks!

Can you post a link to a website that shows the type of behavior your trying to achieve? It's a bit hard to understand what you're asking in this question. I'm using this theme. At PORTFOLIO part, I want the image can zoom with text when I hover. I already done the text part. Just got a trouble about the image. I tried many times, hope someone can help me.

Are you talking about the image that opens after you click on it? Like this one?
