The good news is that if you’re learning about this for the first time, Google has announced that Gmail for iOS will now automatically block images in emails. This means that any image attachments in these emails will be blocked from loading. Instead, if you want to see them, you’ll have to do so manually.
This isn’t exactly a new thing as Google had previously rolled out that feature to its other platforms, such as Gmail on the web, so it’s good to see it make its way to mobile as well. This seems to be in response to an issue with the Superhuman subscription email service that let users track the location of a recipient after they opened a message.
This was initially discovered by former Twitter executive and designer Mike Davidson who penned a blog post about it. That being said, we should point out that the setting to block images in emails will be turned off by default. You will need to dive into your Gmail settings if you want to block it.
