Gmail already proxies images in emails to their own servers.

  But they still only request them when the client views them and not beforehand, so the view tracking still works and even has the proper timestamp for that.

  That still tells the spammer you opened the email. I also doubt they do so for third party email accounts, which can also be used in the gmail app.
