Gmail: Images Now Showing
Gmail now offers users the ability to choose to automatically display images within their emails. Previously, Gmail would prompt to you display images one time, or to always allow from the specific sender. Google enforced this policy to prevent any type of misuse from senders and marketers as images would be hosted on recipients servers.
The ability for recipients to control the images could potentially provide marketers with info such as your IP address, your browser/mobile device, the page URL you are coming from, just to name a few. Google has now allowed images to always be visible by improving the way their servers handle images. Instead of hosting the images from the recipients in, they are now cached within Google's secure servers to ensure there is no risk of any misuse.
Essentially what this means for end users is that you can comfortably access all your emails and view images safe and secure without the risk of outside exposure or annoying popups asking for permission. If you still prefer to opt-out of having images automatically displayed, you can do so by following these quick instructions.
