When you run the WordPress Import Tool from an .xml file belonging to another website (included dummy data from template developers), WooCommerce product images don’t get imported! HOW ANNOYING! Here’s how I fixed it.
The issue: after importing, WooCommerce products have no images
The solution: use the core WooCommerce import/export functionality
That’s it 🙂
Go to WordPress Dashboard > Products > Import (or Export) and follow the instructions.
This is a new functionality introduced since WooCommerce 3.0 and it’s working like a charm.
For more advanced import/export, automatic updates from server and more complex functionalities, take a look at http://www.wpallimport.com/woocommerce-product-import/, a product used by many of us.
