Have you ever wondered why Gmail asks you before showing images in emails? We did this to protect you from unknown senders who might try to use images to compromise the security of your computer or mobile device.
But 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.
Similar to existing features like default https access, suspicious activity detection, and free two-step verification, image proxying is another way your email is protected. This new improvement will be rolling out on desktop starting today and to your Gmail mobile apps in early 2014.
