If you’re concerned about leaks and users screen capturing the content on your thumbnails, you can make their thumbnails smaller. Apply this at the user role or user level.

Site configs default to 200x200, but configs can be adjusted to make them as small as 100x100, 50x50, or 20x20.

Note: This option is available because we do not watermark thumbnails in CORE due to the processing requirements and performance effects it would have on your site.
