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:
Choose "manage file display" next to Image
- Pick a View Mode, let's say "Small"
- 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 "Rendered file" formatter
- Choose "Small" 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?
