replace image

Currently, there is no way to replace an existing image. This is strange, because when you edit a video, you can change the video url. This option should appear when the user clicks "Edit Media" if they have permission. I am also requesting a new permission for this.

Is there a way to replace a image in the media gallery? I have links going out from the site so I would prefer to not have to upload a new one as I would have to relink. I have FTP access to the server.
