Using WooCommerce to sell online is a sensible move because it’s strong in a wide variety of ways. It’s 100% free (and built on a free CMS in WordPress), compatible with countless other plugins, easy to use, flexible, and quite powerful — even with no custom configuration. But no eCommerce system, no matter how good, will do everything for you by default. Sooner or later, you need to get involved, take charge, and make some necessary changes. WooCommerce product image size should be optimized for optimum results.
