Gmail to cache and auto-display images. What does this mean for you?

the graph titled "New Gmail, images auto-displayed" makes it seem like the user opening the email will cause the open count, but this is incorrect.

As soon as gmail receives the email, they will cache the image link. All images will always show an open count of 1, and only 1, regardless of whether or not a user ever actually opened the email.
