Create Product for woocommerce, image issue

Hi All,
I’m trying to create a product in woocommerce with an existing image from my wordpress website (same wordpress site). But I’m unable to fill in the module correctly for the image. using the URL on the wordpress site isn’t working when I use mapping feature (no image added to the product). If I add the url + name… this is working but this creates a new picture in the wordpress media gallery and this is not what I want. I want just reuse the existing picture. How should I do? What should I fill in the module. You can see what is not working on the screenshot.
Thanks for your help!
