Change image urls

So I have a thousands of images with english product names. For some reason during a transition I lost the other image languages. I also lost the memory of what app or tool I used to make it work.

Essentially I want to change: https://duschgardiner.se/wp-content/uploads/sites/6/2019/06/19931-Bamboo-Bath-Shower-Curtain..jpg

To Swedish: https://duschgardiner.se/wp-content/uploads/sites/6/2019/06/19931-Bambu-Duschdraperi..jpg

They have the same SKU/ID "19931"so that is How i tracked it and matched everything the last time.

Is there an app? Do you have a solution?
