Reply To: Inconvenientes con las miniaturas en el blog

Hello,

As I mentioned in my previous reply the image thumbnails are controlled from Settings >> Media.

You can try increasing the size of thumbnails from there. Also after changing the Image Size as per your requirements from Setting >> Media run this plugin to resize all your existing images to the new size: https://wordpress.org/plugins/regenerate-thumbnails/

You will not lose any changes because the product thumbnails are controlled by WooCommerce and it will not affect them.

You can take a complete backup of the site before making changes.

Best Regards.
