WordPress Product Upload Automation

My WordPress / WooCommerce site needs products to be automatically uploaded and synced say once a week, from a supplier CSV database direct to the Website keeping products and pricing accurate . a lot of images are already on the site, but I do wish to add a large amount of product from a CSV file to the site but don't know how to handle the images. If this job is done well on my smaller site, I do have another very similar job for another site.
