Hi @bencik85,
Whilst I couldn’t locate a plugin which would allow you to add a custom product image link in WooCommerce you could create your own code to change this as the images are loaded from this file below.
https://github.com/woocommerce/woocommerce/blob/master/templates/single-product/product-image.php
If you created a custom meta field on a product which could take an image URL you could then edit this file to use that custom URL.
If you need assistance customizing WooCommerce one of these services could help with this and for this type of task Codeable would be a good choice.

I hope this helps.
