Change Image Size/Block Height

Hi, I’m trying to reduce the size of the images in the slider. They all display the same size now, but I want to reduce the size of all of them (or reduce the size of the entire block… whatever is easiest.) I’ve managed to successfully reduce the picture size, but the add to cart button and price stay in the same position and the smaller image seems to now be aligned to the left. How can I get the images centered again?

Here’s the code I used to reduce the image size:

.wpcsp-thumb {width: 250px!important;}

Feel free to let me know if there’s a better/easier way to do that instead too and get the images centered. Thanks!
