Show file name in exported CSV file?

I'm using this module toexport a Views list of content as a csv file.

The content has a image field (multiple values in it) then the csv data shows nothing for the images. I need to output the name of the image file.

I tried adding a a Relationship field: File Usage: File but I get duplicated rows...

I need to output a CSV file, something like:

TITLE, IMAGES
"my dog title" , "dog-picture-1.jpg, dog-picture-2.jpg"
"my cat title" , "cat-picture-1.jpg, cat-picture-2.jpg"

How can I sort this out?
