Gmail Now Caching Images

It is being widely reported that Gmail is now caching images.

As of sometime in the past day or two, it seems that Google has modified Gmail to rewrite the URLs for images in inbound HTML email messages. It looks like they're using some sort of transparent caching proxy process, where the address for an image URL query is rewritten to go through their own servers.

Ah, that was a step leading to this update from Google:

Thanks to new improvements in how Gmail handles images, you’ll soon see all images displayed in your messages automatically across desktop, iOS and Android. Instead of serving images directly from their original external host servers, Gmail will now serve all images through Google’s own secure proxy servers.

So what does this mean for you? Simple: your messages are more safe and secure, your images are checked for known viruses or malware, and you’ll never have to press that pesky “display images below” link again. With this new change, your email will now be safer, faster and more beautiful than ever.

A clarification on open rates from Gmail accounts:

Internet 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. What won’t get tracked, however, is other user data like users’ IP address. So this seems to do more to protect privacy without leaving marketers totally in the dark.
