I would like to know how to make my small product images (the ones that show up in a grid) and my main product images a little smaller. I don't have access to larger images for my products, so many of the images look grainy and blurry at the default size. Messing around with the WooCommerce image size settings doesn't seem to have any effect, so I'm assuming I need to make some CSS changes. Can you please point me in the right direction? I know that the left-hand "container" where the main product image shows on a product page is a fixed width, so that can't be easily changed. I'm fine leaving the grey surrounding box around the image the same size, but I just need the images themselves to be smaller. Thanks in advance for your help!
