A study by DEGs confirmed messages from wordtothewise blogger, Laura Atkins, that "Google is rewriting links to images. This rewriting seems to occur during the delivery process. Previous messages that are currently in arent mailboxes show this tracking."
For global images, this means that only one user must open the mail and pull the images from the server. In the case of image tracking, each image file name is unique. Each new discovery will lead to the fact that Google will capture a uniquely named image. The result is that senders can track the first open, but after that it does not open. "
