Use Mass Action and/or Product Update Plugin to change images_path

-- url of the page with the problem -- : shop.cwpoolsandspas.com

I need to sync images entered into my Point-of-Sale software for existing products with Hikashop. I have created a cron job to automatically FTP the images to Hikashop image directory and then it creates .csv file to update the Hikashop products (via the Product Plugin). But what column name do I use to update images_path in Hikashop?

When I test the .csv file import in In Mass Action none of the below work:
product_code,images_path
generates a column/value mismatch error

product_code,images
processes successfully but doesn't update the product image

product_code_images_name
processes successfully but doesn't update the product image

Is it possible to update images on existing products using either Mass Action or Product Update Plugin?

Thank you

Using the product Import Plug-in to update images works for my main products but not for my existing variants. The fields in my upload .csv file are

• product_code
• product_name
• images
