Unless, of course, the image has an email-unique key in the URL somewhere.

I have edited that sentence to say "where the request came from" rather than "who has actually requested it".

Overall though, its still an improvement. A key in the URL does verify that the email address is deliverable, which isn't nothing, but still can't be directly correlated with an IP address or other tracking data.
