For the foreseeable future, the delete option for images and folders in the image Library has been removed. This functionality has been removed as there have been instances of images being moved or removed causing the images to disappear from the content containing them.

Starting this February (earlier this month), direct access to the CDN has also been limited to avoid these issues. This can only fix images "Disappearing" for those images/folders added to the image Library after these updates. Prior to these changes, Images that have already been moved or deleted from their desired location may still be seen in content due to being cached. These cached images may last for up to 120 days, though will eventually return "404 - File or directory not found."
