Product Image Way Too Large!

Hi,

I’m having a real headache in trying to get single product images smaller on my site. I’m using the Avada theme (requested by a client) and I can’t get the image smaller. I’ve tried various things, regenerating thumbnails, changing the settings in woocommerce and inserted the following css:

.fusion-flexslider .slides img {
height: 150px;
width: 150px;
}

However, after inserting css I find it overrides my blog images which I don’t want it to do. I would ideally like the image 3/4 of the size in a central position.

Please see attached screenshot:
