Hi Greg,

I’m afraid I may indeed have to disappoint you on this one. Code-level support is something we can’t do as a free support service and I’m afraid your question does categorize as code-level support.

Do note however, that woocommerce has some options for image sizes in woocommerce->settings->catalog and then at the very bottom of that page. It could be that you’ll need to regenerate your thumbnails (using the regenerate thumbnails plugin) after changing the sizes before they will actually take effect on your website.

I’m not entirely sure if the sizes available for editing down there include the one you need but if so it would be a shame to css it.

Kind regards,

Kevin
