fields with Image styles only showing placeholder I've got some images that's set to be shown in specific image styles. They appear fine on each node but in teasers and views I only get a placeholder.

The console in Chrome's inspector says:


  Failed to load resource: the server responded with a status of 500 (Internal Server Error)


The Files folder has permissions set to 775. Should be good, right?

Any ideas?
Here is an overview of how file permissions should be set on a Drupal installation: https://www.drupal.org/node/244924

If you scroll down there is a shell script that you can install on your server and it will fix all file/folder permission errors.

Your issue is definitely a folder permission error, Drupal has to be able to write to the /files folder. It makes new directories for each style, each image, each size so one folder may exist but the others may not be able to be made.
