How to find node that a file is attached to There is a file that I want to find the node it is attached to, or at least the user that submitted it.

I was able to create a view that finds the file itself but when I a field for node id, it displays nothing.
Create a view of files. 

Add a relationship 'File Usage: Content'

Add a field 'title' and set the relationship on it to the one you created above.

Adjust the rest of the view as needed, ie add contextual filter Content: Image:fid
