Add Extra Product Image Sizes Or Change Pop-Up Box Size (Images Cut Off)

Hi!

I’m using the WooCommerce Notification Plugin to display recent sales on my site, however, I’m having trouble displaying the image properly.

Under the “Products” tab, is it possible to use a product image size other than the 3 included (i.e. 100×100, 150×0 and 500×0)? Unfortunately, my site uses images that aren’t perfect squares and, as a result, the images are being cropped on both the top and bottom when shown in your sales pop-up.

Is it possible to use a different size? Either via CSS or otherwise? If not, is it possible to change the dimensions of the actual pop-up box via CSS so the entire image is shown?

Thanks!
