Slideshow hides/deletes everything in a view

I'm trying to use Views Slideshow with Views Slideshow Galleria, but I cant even show a single image. I'm following this tutorial step by step:

Over minute 13, he gets an image, but I'm getting... Nothing. If I set just Title in Fields filtering by Slideshow Image, I get a fine list of this contents, but when I set Slideshow Image in Fields, I'm getting nothing, not even titles that were working fine.

Thanks for your help!
