Import files (images) from one database to another not working

Hi

I switched mongodb database and I’m trying to migrate my old data to my new mongodb. I’m using mongorestore to import .bson files to the new mongodb. I’ve managed to restore all my collection but one of the collections uses files. So, I’ve also imported the fs.chunks and the fs.files. However, the images do not display. When clickin on the image link in the Parse dashboard, I get a blank page.

Any ideas why my images are not showing ?
