Change the image url

Hi Good People,

I love your plugin and I am inspired to do more…

How can I change the main image url to a new (keep filename)

I did read this topic but I can not figure out the solution: https://www.ads-software.com/support/topic/possible-to-serve-different-featured-image-to-merchant-center-than-in-shop/

So I want to replace all urls of my main images from /wp-content/xxx.xxx-xxx/year/mont/<filename.jpg> to

/image/<filename.jpg>
(And is there a way to also include variants or is that implicit?)
Thanks a million for helping out!
