remove_remote_media.php [options]
Removes remote media. In most cases, (if not all), an URL will be kept for the original attachment.
In case the attachment is an image its thumbs will be removed as well.
-l --limit [date] This is a timestamp, format is: yyyy-mm-dd (optional time hh:mm:ss may be provided)
-a --all By default only remote attachments will be deleted, by using this flag you will remove oembed previews and alike
-i --image Remove image only attachments (will ignore oembed previews and alike)
