No Chrome extension can know which images are being used to track email opens. If you want to disable that sort of tracking you should disable images/external resources completely. Otherwise you're just getting a false sense of security.
BTW what is the point?<p>I mean, one can legitimately want that <i>they</i> do not receive the tracking information. But are there any real security implications, like siphoning off any unauthorized data, facilitating spam, etc?
google already grabs the images via image proxy.. <a href="http://gmailblog.blogspot.com/2013/12/images-now-showing.html" rel="nofollow">http://gmailblog.blogspot.com/2013/12/images-now-showing.htm...</a>
Isn't this redundant unless I accept images? I get:"Images are not displayed. Display images below - Always display images from webmaster@ibmverse.com" (for example).
I generally use Thunderbird and while I have not checked what it does in all cases, it generally flags when there is remote content and provides options regarding loading it. I'm happy with that. I know many folk of course use web based mail readers, and this is directed at them, but if its a big issue using a product like Thunderbird may be the way to.

(The spokesperson declined to be quoted.) Instead, they said marketers who track open rates through images will still be able to do so — indeed, they suggested that the data might be more accurate now since open rates will count users who read the emails but don’t load the images."<p>Sounds like Google made sure tracking works even when users attempt to evade it.<p>But another quote in the same article still talks about pixels:<p>"MailChimp can still detect the first request for the open-tracking pixel."
