How is Image Collection Field Link Generated?

When inserting an image to a wix collection image field. It results in a wix image link like below.


How is this image link generated? Reason being, I have imported about 2,000 entries, and I would rather not attach each image individually.

Wix unfortunately renames anything you add into the Media library, so when users download anything or you want to get the url, it names them with a Wix assigned scrambled filename instead of what you named the file in the system.
