Rendering a generic file field containing an image Drupal 7.34
Media 7.x-1.4
Views 7.x-3.8

I have a generic file field. Sometimes the uploaded file is an image, and in these cases I want to render it in a View as a thumbnail.
So I do the following:


Go to admin/config/media/file-types

Choose &quot;manage file display&quot; next to Image

Pick a View Mode, let's say &quot;Small&quot;
Check the box next to the Image display
Pick my desired Image style from the dropdown in the display settings


Add the file field to my View

Choose &quot;Rendered file&quot; formatter
Choose &quot;Small&quot; view mode
hit Apply




…and the view puts a big blank space where the image should be.
I've checked the database, and Drupal has correctly identified my upload as image/jpeg. It opens fine in the browser.
If I choose a different formatter in the view, like Table of files or Generic file, it shows up fine.
If I choose a different formatter in the file display settings, it still shows nothing in the view.
Am I misunderstanding something? What's going on?
Check admin/config/media/file-types/manage/image/display/media_small and check that File is actually being displayed and not set hidden.
