Gmail on iPhones gets this new feature

In its latest update for iOS, Gmail now allows users to block images from displaying automatically.

As described on the Apple App Store, with the version 6.0.190811 Gmail for iOS, users can choose to be asked before external images are displayed automatically.

To enable the setting for new incoming messages, head to Settings > choose the account > Images and select Ask before displaying external images. The feature is helpful when you are on a weaker connection.
