Unless you use an iPhone, then there is no way to shut off images in gmail. Seems a bit strange that they'd not have that feature, when gmail was the first big provider to disable images by default.
That is inaccurate. I have disabled image loading in Gmail and this is reflected in the web interface, the Gmail Android app, the Apple Mail app, and very likely in all other mail clients. Just to be clear, you do not need an iPhone to shut off images in gmail.
I mean in the gmail app for iphone. Gmail images are off when I use a desktop, they're off when I use the andriod app, but I was surprised to see images in email when using the gmail iphone app.
Last time I went searching, I found google documentation that said there are no image options for the iphone app.
The feature is present for some time now on both major platforms, both in the Gmail app and the built-in Mail app, on (some) 3rd party mail clients, and in the web interface.
Does it work in Gmail? Since it doesn't load images until I athorize: https://i.imgur.com/RZ93VIU.png
